Module 1: HIV Information Broad objective At the completion of this module, participants shall acquire information and knowledge on HIV infection, transmission, progression, management and prevention according to the national HTC curriculum. Specific Objectives Define HIV, HIV infection and AIDS Describe the epidemiology of HIV in Adults and Children Describe basics of human immune system; Describe the modes of HIV transmission; Describe biology and natural progression of HIV in adults and children; Describe common HIV related conditions Describe HIV prevention strategy including stigma reduction Definitions What is HIV? HIV stands for Human Immunodeficiency Virus. It is a retrovirus. HIV Infection is the state where the virus is in the body. In most instances this is the asymptomatic state, which is a prelude to AIDS. AIDS stands for Acquired Immune Deficiency Syndrome. “Acquired” means it is transmissible, and “Immune-Deficiency” means it damages the body defense system “Syndrome” refers to a group of illnesses. Unit 1: Overview and Epidemiology Historical background of HIV 1981 – Doctors in the United States recognized Kaposi’s sarcoma (KS) in homosexual males, a condition previously unreported in healthy adults. Later they recognized that all these patients were immuno suppressed. 1983/4 – Scientists described the cause of this acquired immunodeficiency syndrome (AIDS) as a retrovirus: 1. Lymphadenopathy Associated Virus (LAV). 2. AIDs Associated Retrovirus (ARV). 3. Human T-lymphotrophic Virus ? (HTLV-?). Historical background of HIV cont’d 1984– The first case in Kenya was described 1986 – Human Immunodeficiency Virus (HIV) was accepted as the international designation for the retrovirus in a WHO consultative meeting 1996 – ARVs became available in the world. 1997 – ARVs became available in the private sector in Kenya. 2003 – ARVs became available in public sector in Kenya. 2006 – Approximately 90,000 Kenyans are taking ARV treatment. GLOBAL AIDS INDICATORS (UNAIDS 2008) Globally, there were an estimated 33 million [30 million–36 million] people living with HIV in 2007 The annual number of new HIV infections declined from 3.0 million [2.6 million– 3.5 million] in 2001 to 2.7 million [2.2 million–3.2 million] in 2007. Overall, 2.0 million [1.8 million–2.3 million] people died due to AIDS in 2007, compared with an estimated 1.7 million [1.5 million– 2.3 million] in 2001. Southern Africa continues to bear a disproportionate share of the global burden of HIV: 35% of HIV infections and 38% of AIDS deaths in 2007 occurred in that sub region. Altogether, subSaharan Africa is home to 67% of all people living with HIV. Estimated Number of Women, Young, Children Newly Infected With HIV During 2007 Women account for half of all people living with HIV worldwide, and nearly 60% of HIV infections in sub-Saharan Africa. Over the last 10 years, the proportion of women among people living with HIV has remained stable globally, but has increased in many regions. Young people aged 15–24 account for an estimated 45% of new HIV infections worldwide. An estimated 370 000 [330 000–410 000] children younger than 15 years became infected with HIV in 2007. Globally, the number of children younger than 15 years living with HIV increased from 1.6 million [1.4 million–2.1 million] in 2001 to 2.0 million [1.9 million–2.3 million] in 2007. Almost 90% live in sub-Saharan Africa . HIV among children It is estimated that more than 90% of children living with HIV acquired the virus during pregnancy, birth or breastfeeding—forms of HIV transmission that can be prevented. A small fraction of HIV infections in children are caused by contaminated injections, the transfusion of infected blood or blood products, sexual abuse, sexual intercourse (although this is a significant mode of transmission among adolescents), or scarification In 2007, an estimated 270 000 [250 000–290 000] HIV-infected children younger than 15 years died because of AIDS—more than 90% of them in subSaharan Africa Epidemic update: Kenya Indicator National adult prevalence: 15 - 49 years Total Number of HIV infected people NASCOP 2005 6.7% Women-8.7% Men 4.6% 1.25Million KAIS 2007 7.4 % Women 9.2% Men 5.8% 1.4 Million (between 15 – 64 years) Number of children infected Number on ART increasing End August 2006 120,000 Adults-88589 Children-6744 140, 000 (15 – 64 years) Number needing ARV 250,000 390,000 (15 – 64 years) Epidemiology of HIV/AIDS in Children (under 15 yrs) Global Sub-Saharan Africa Kenyan estimates No. living with HIV 2.5 million 2.25 million 100 – 150,000 No. Newly infected 700,000 616,000 34,000 No. AIDS deaths 450,000 18,000 500,000 Epidemiology/Impact of HIV/AIDS in Kenya 60% medical beds- HIV/AIDS 40% Paediatric beds-HIV/AIDS >50% TB patients – HIV + >25% STI patients – HIV Health workers face both the medical and social challenges of HIV/AIDS on a daily basis HIV transmission modes HIV is mainly transmitted: through unprotected sexual intercourse with an infected person through exposure to blood, blood products, body fluids and other tissues, e.g. organ transplants and during pregnancy, birth, or breastfeeding from infected mother to child The fluids from an infected person that can potentially transmit HIV include: Blood Semen Vaginal fluid Breast- milk Transmission modes Transmission route % Sexual intercourse 80-90 Mother-to-child-transmission 5-10 Blood transfusion 3-5 Injecting drug use <5 Health care – e.g.: needle stick injury <0.01 Incidence and modes of transmission Summary Over the past 2 decades HIV has spread worldwide with devastating epidemiological consequences particularly in Sub Saharan Africa MTCT is the main mode of transmission of HIV infection to children HIV/AIDS is a major cause of morbidity and mortality. Unit 2: Human Immunology & Biology of HIV Specific objectives Define the cells involved in the immune system and their function. Know the host immune response during and after infection. Basic HIV structure. The significance of genetic diversity and classification of HIV. The replication cycle of HIV. The target sites for antiretroviral drugs. Components of immune system 1 Found in blood and tissues 2 White blood cells (WBC)- key players in immune response (humoral and cellular) – Macrophages act as clearing cells – Neutrophils attack bacteria – Eosinophils attack helminths (and mediate allergies) – B-lymphocytes make antibodies – T-lymphocytes • Responsible for attacking viruses, fungi and some bacteria • T helper cells central in orchestrating function of other immune cells • T killer cells are able to destroy infected cells How HIV affects the immune system 1 HIV attaches to cells of the immune system with special surface markers called CD4 receptors 2 Immune cells with CD4 receptors include: T-helper Lymphocytes Macrophages Monocytes Dendritic cells Microglial cells HIV effects on immune system The hallmark of HIV/AIDS is profound immunodeficiency as a result depletion of CD4+ T lymphocytes. The CD4+ T cell dysfunction is two fold - Reduction in numbers - Impairment in function Types of HIV There are two types of HIV: HIV-1 (found worldwide and is the main cause of the epidemic) The strains of HIV-1 can be classified into three groups : the "major" group M, the "outlier" group O and the "new" group N. These three groups may represent three separate introductions of simian immunodeficiency virus into humans. Group O appears to be restricted to West-central Africa and group N - discovered in 1998 in Cameroon - is extremely rare. More than 90% of HIV-1 infections are due to HIV-1 group M. Within group M there are known to be at least nine genetically distinct subtypes (or clades) of HIV-1. These are subtypes A, B, C, D, F, G, H, J and K. HIV-1 Subtypes HIV 2 Found mainly in parts of West Africa, Mozambique and Angola) HIV-2 causes a similar illness to HIV-1including AIDS. It is however less efficiently transmitted, rarely causes vertical transmission and is less aggressive, with slower disease progression. In Kenya the commonest type of HIV is type 1 with Subtype C as the most predominant in eastern Africa. However other subtypes are also found and recently HIV type 2 has also been discovered in the country. HIV 2 cont’d Until about 1994, it was generally thought that individuals do not become infected with multiple distinct HIV-1 strains. However, it is now thought that "superinfection" does occur. In these cases, the second infection occurs several months after the first. It would appear that the body's immune response to the first virus is sometimes not enough to prevent infection with a second strain, especially with a virus belonging to a different subtype. It is not yet known how commonly superinfection occurs, or whether it can take place only in special circumstances. STRUCTURE OF HUMAN IMMUNODEFICIENCY VIRUS Has an outer double lipid membrane, (derived from the host membrane). The lipid membrane is lined by a matrix protein. The lipid membrane is studded with the surface glycoprotein (gp) 120 and the transmembrane gp 41 protein. These glycoprotein spikes surround the cone-shaped protein core. The core (capsid) is made up of several proteins : P24 (the main protein) and P16 P9 and P6 Within the capsid are two identical single strands of RNA (the viral genetic material). Viral enzymes HIV Replication Cycle Summary HIV attacks the Immune system of human being and leads to profound immunodeficiency. Rapid replication of HIV causes genetic diversity of the virus. Knowledge of the HIV structure is important in understanding the mechanism of ARV drugs Unit 3: Natural Progression of HIV Objectives Describe stages of HIV progression - serocoversion, asymptomatic, symptomatic and AIDS phases Be able to stage HIV infection by WHO classification Clinical Manisfestations Acute HIV infection Most people infected with HIV do not know that they have become infected. After the infection; virus is disseminated via blood to CNS and lymphoid tissue. The Virus trapped in lymphoid tissue rapidly replicates. This is accompanied by patient’s immune response with concomitant development of antibodies to HIV antigens usually within 6 weeks, but may take up to 3 months, after the infection. This “sero-conversion” is when a person recently infected with HIV first tests positive for HIV antibodies. Some people have a “glandular fever” like illness (fever, rash, athralgia, fatigue and lymphadenopathy) at the time of seroconversion. Clinical Manifestations cont’d Asymptomatic HIV infection In adults, there is a long, variable, latent period from HIV infection to the onset of HIV related disease and AIDS. A person infected with HIV may be asymptomatic for 2 to 15 years The vast majority of HIV- infected children are infected in the peri-natal period. The period of asymptomatic infection is shorter in children than in adults. A few infants become ill in the first few weeks of life. Most children start to become ill before 2 years of age. A number of children remain well for several years. Initially CD4 cell levels are high but gradually declines and immunity starts weakening. The patients are asymptomatic but are infectious. Clinical Manifestations cont’d Progression to HIV disease and AIDS As disease progresses without any intervention, production of CD4 cells cannot match destruction.CD4 cell count decreases and immune system starts failing leading to increase in viral load. Consequently, there is increased risk of HIV-related diseases and conditions. Almost all HIV infected people will ultimately develop HIV-related disease and AIDS. Some HIV- infected individuals progress more quickly than others to HIVrelated disease and AIDS. The World Health Organization (WHO) classification of HIV/AIDS is internationally accepted as the standard classification, for use in diagnosis and treatment. The same is shown in the next slide.

Advocacy and lobbying for societal change and reduction of denial Condom promotion and availability Sexually transmitted infection management Voluntary counseling and testing. Prevention of mother to Child Transmission Blood Safety Stigma Reduction Harm Reduction for Injecting drug users Secondary Prevention This includes the management of the HIV positive person starting to develop HIV/AIDS. This is a holistic approach that involves physical, social, psychological and spiritual interventions. The provision of sexually transmitted diseases care. The provision of Anti-Retro viral medications. Reducing fertility. This alludes to encouraging women who have the infection not to have children. Health promotion strategies must be pursued aggressively The ABC of HIV prevention A Abstain from sex B Being faithful to your partner. C Condoms use (correct and consistent use) D Discuss about HIV testing Drugs for STI Delay sexual début E Empowerment in negotiating sex Adherence to HIV Therapy 61 Adherence vs. Compliance (1) Adherence The act or quality to stick to something, steady devotion or the act of adhering. It describes the patient’s behavior of taking drugs correctly; in the right dose, with the right frequency, and at the correct time. A critical aspect of adherence is the patient’s involvement in deciding whether or not to take the drugs. [Patients acceptance to take an active role in own health care]. 62 Adherence vs. Compliance (2) Compliance The act of conforming, yielding or acquiescing. Compliant patients will do what he or she has been told by the health care provider. [There is lack of sharing in the decision making]. 63 How to Promote Adherence Counseling—Very vital Participation of the patient in a plan of care. Don’t rush to ARV, patient must be ready! Information/Education/Communication on ARV drugs: Provide simple written information Educate and motivate: basic drug info, importance of adherence, timing of medications, drug interactions, etc Warn patients about common side effects 64 Outcomes of optimal adherence Positive treatment outcomes. Slower clinical progression of diseases Decreasing viral load. Economic benefits – Minimal drug. Resistance reduced utilization and costs of drugs and services. Improving quality of life and therefore functioning. ( Physical, Psychological, Social etc… ). 65 Predictors of suboptimal adherence; Active psychiatric illness (especially depression) Active drug and/or alcohol use History of non-adherence Medication side effects Lack of education about treatment. 66 67 Steps Toward Adherence to Antiretroviral Therapy (ART) 1. Acceptance of ART (Readiness) 2. Ability to take and adhere to ART 3. Maintenance of adherent behavior 68 Factors Affecting Adherence Disease Characteristics Prior OI Patient/Provider Relationship Trust and confidence Drug related Number, food/ fluid restrictions, side-effects, Pill burden, Drug interactions, Storage needs Clinical setting Patient variables Sex, age, education, alcohol, social support, readiness Lifestyle, Socio-Economic, Traveling Forgetfulness, depression 69 Friendly, supportive non-judgmental staff confidentiality, convenient appointments Some Barriers to Adherence Communication difficulties Low literacy, if written Unstable living conditions- lack of social support Discomfort with disclosure of HIV status, which may became known when medications are taken Stigmas, denial and discrimination Difficulties in accessing adequate health care Competing priorities- Work, Child care, lifestyle [may be seen as more pressing than taking medications regularly] Alcohol and drug use Depression 70 KEY POINTS ON ADHERANCE ARVs not a cure for HIV/AIDS Life long treatment. Taken with specific timing. Side effects No sharing of drugs Appointment dates. Avoid re-infection Balanced diet Nutrition Key points on Adherence continued Avoid herbal medication /Treatment, alcohol, Cigarettes. Be wise and informed in faith/miracle/prayer healing. Disclosure- encouraged for support. Initiating ARV Therapy (1) Patients /Guardian involvement in planning the treatment regimen is critical Patients Guadian should help in making final decision of when to initiate ARV therapy Initiate ART after counseling has been given regarding specific issues relevant to his/her own clinical situation. 73 Initiation of ART in Children 1.An exposed child whose mother is on ART: At birth, give NVP & AZT syrup septrin at 6 weeks. Do a PCR, if NEG, stop AZT and continue with NVP and septrin if still exposed. If child turns +ve, start ART. At 9 months, do an Antibody test, if child turns +VE, start ART. TYPES OF HIV TESTING 1.Client initiated HIV Testing & Counselling. (VCT) 2. Provider-Initiated HIV testing & Counselling. 3. Other Types- Self Testing,Required HIV testing eg by Millitary, court of Law. Other Types of testing continued In Blood and Tissue Donation HIV Testing for Research & Surveillance. LEGAL IMPLICATION ON TESTING Supportive documents : • Public Health Act, • HIV & AIDS prevention and controll Act (2006 ) • Constitution of Kenya :Bill of rights. LEGAL IMPLICATION CONTINUED NB/ All HTC Services should be conducted with the best interest of the client. HTC Should never be coercive or mandatory. CORE PRINCIPLES TO HTC • Consent- Should be informed consent. • Confidentiality – Sharing of information should only be done with the consent of the client. • Counselling – Pre test and post test counselling.( According to individual/couple/family needs) CORE PRINCIPLES TO HTC cont’d: Consent is based on sufficient, Accurate, and Voluntary information. HIV&AIDS prevention and controll Act provides for testing without consent for those not able to give consent. In children, get consent from the parents/guardians. CORE PRINCIPLES TO HTC cont’d: Persons with disability preventing them from giving consent should be tested with consent of parents /guardians / partner/caretaker. CORE PRINCIPLES TO HTC cont’d: The only circumstances where consent for HIV test is not a requirement : • In requirement for testing under the provisions of a written law. • Unconscious patient and unable to give consent, • Test medically necessary for a clinical diagnosis. STIGMA REDUCTION Encourage disclosure. Psycho- social support eg joining support groups/clubs etc. Open group discussions. Economic support. Proper counselling- to client and spouse/caretakers. Health Education and couselling to employers,teachers,workplaces etc. THANK YOU PREVENTION OF MOTHER TO CHILD TRANSMISSION OF HIV BACKGROUND Over 33 million people are living with HIV/AIDS worldwide, and about two-thirds or 22.5 million of PLHIV live in sub-Saharan Africa. HIV/AIDS mainly affects people of reproductive age and increasingly affects women, who now account for 69% of new infections in sub-Saharan Africa, where women are 30% more likely to be living with HIV/AIDS than men, and young women aged 15-24 are nearly four times more likely to be infected than their male counterparts. Young, married women, who are often monogamous, have become one of the groups most vulnerable to HIV in the region. This requires new and rapid responses that broaden the focus beyond traditional “high risk” groups like commercial sex workers, truck drivers, and drug users. BACKGROUND cont’d: To reach young married women, who may not be aware of their vulnerability, HIV/AIDS prevention, care and support activities must be integrated into already established health services that are used by the general population. An estimated 370 000 children world-wide became infected with HIV in 2009, down from a high of 630,000 children in 2003 — most through MTCT. The risk of an HIV-infected mother passing the virus to her infant during pregnancy, labour and delivery or in the postnatal period is 1 in 3 if nothing is done to reduce this risk. BACKGROUND cont’d: Of the one-third who become infected, about 5-10 babies will be infected during pregnancy, 15 will be infected during labour and delivery while 5-15 will be infected during breastfeeding, largely being dependent on breastfeeding practices and on the duration of breastfeeding. Most children born with HIV die before they reach their fifth birthday, with 50% not surviving beyond two years. ARV prophylaxis pregnancy, labour and delivery and during breastfeeding period can substantially reduce MTCT. In resource poor settings, it is critical that prevention procedures be integrated into existing sexual and reproductive health (SRH) and maternal and child health (MCH) services, reaching as many women as possible and lowering transmission rates. BACKGROUND cont’d: HIV/AIDS transmission from mother to child in Kenya is one of the biggest health and development challenges in Kenya. According to the 2008/9 Demographic and Health Survey, 6.3% or over 1.4 million Kenyan adults were living with HIV/AIDS in 2010. There has been stabilization of HIV sero-prevalence in Kenya. In 2005, the prevalence rate was estimated at 5.9% and as per the 2006 statistics the prevalence rate among adults had dropped to 5.1%. According to 2007 Kenya AIDS Indicator Survey (KAIS) the HIV sero-prevalence in Kenya is 7.8% among adults aged 15-49 years, being higher in women (8.7%) than in men (5.6%), Young women are more vulnerable in Kenya than men, as evidenced by a nearly 9% prevalence rate among women and under 5% among men. Infants and young children under 15 years account for 16% of all new HIV infections mainly as a result of MTCT. Most of the new infections occur among young people, in whom the main mode of transmission is through sexual intercourse. Magnitude of HIV in Pregnancy in Kenya Kenya National AIDS/STI Control Programme (NASCOP) estimates that there were 1.55 million babies born in 2011 in Kenya and that as many as 6.3% of pregnant women in Kenya were living with HIV/ AIDS. With an estimated population of 38.6 million in the year 2010, the number of HIV - exposed babies is estimated to be 97,272, and at least 38,900 HIVpositive babies are born, assuming a 40 % transmission without any interventions Risk of Transmission of MTCT In Kenya, an estimated 37,000 to 42,000 infants are infected with HIV annually due to mother-to-child transmission. This can occur in utero, during labour and delivery and through breastfeeding. During pregnancy, about 5 to 8 percent of HIV-exposed babies become infected through transmission across the placenta. Labour and delivery poses the greatest risk for transmission with 10 to 20 percent of exposed infants becoming infected at this time. Breastfeeding also exposes infants to HIV. When mothers breastfeed for 18 to 24 months another 10 to 15 percent of infants become infected. Thus, in non-breastfeeding populations, without antiretroviral treatment, approximately 15 to 30 percent infants will become infected; with prolonged breastfeeding, 25 to 45 percent infants will become infected. Risk factors for MTCT Strong evidence Limited evidence Viral High viral load Viral resistance (theoretical possibility) Viral genotype and phenotype Maternal Immune deficiency (low CD4 count), HIV infection acquired during pregnancy or breastfeeding period Vitamin A deficiency, anaemia, sexually transmitted diseases, chorioamnionitis, frequent unprotected sexual intercourse, multiple sexual partners, smoking, injecting drug abuse Obstetrical Vaginal delivery (compared to elective caesarean section), rupture of the membranes for more than 4 hours Invasive or traumatic procedures: instrumental deliveries, amniocentesis, episiotomy, external cephalic version (ECV), etc., intra-partum haemorrhage Fetal/Infant Prematurity Lesions of skin and/or mucous membranes Breastfeeding Duration of breastfeeding, mixed feeding, breast disease (mastitis/cracked nipples) Oral thrush (baby) Benefits of Preventing Mother-to-Child Transmission of HIV AIDS related deaths are reversing gains made in child health and survival in Kenya. Caring for HIVinfected children has major economic and social impacts on families and health systems. preventing MTCT has the potential to increase the understanding and acceptance of the HIV/AIDS epidemic and those living with HIV/AIDS. Counseling, testing and community sensitization can contribute to reducing stigma. Benefits of Preventing Mother-to-Child Transmission of HIV cont’d: Reduction of MTCT of HIV: - Decreases numbers of HIV infected children - Increases child health and survival - Decreases the load on the health system - Gives an opportunity to improve and expand health services as well as to strengthen the existing health infrastructure Benefits of HIV Counseling and Testing (CT) It promotes behaviour change It enables preventive therapy It promotes access to early medical care It helps to plan for the future The Four-Pronged Approach to PMTCT 1. Primary prevention of HIV infection in women 2. Prevention of unintended pregnancy among HIVinfected women 3. Interventions to reduce transmission from HIVinfected pregnant and lactating women to their children 4. Care and support of women, children and families infected and affected by HIV and AIDS (The PMTCT-plus) Towards virtual elimination of MTCT (eMTCT) elimination of MTCT (eMTCT)- (MTCT rate of <5% among breast feeding populations or 90% reduction in mother to child HIV transmission rates by 2015) is now considered a realistic public health goal and an important contributor to achieving MDGs by 2015 focuses on prevention of new infections and PMTCT is one of the key strategies focuses attention on the reduction of HIV-related illnesses and deaths, and mitigation of the effects of the epidemic on households and communities through key strategic directions namely extraordinary leadership and commitment, Health systems strengthening including capacity building for improved access to PMTCT services and RH/HIV integration. Other components include: community systems strengthening, sustainable financing and regular countdown to track progress. Towards virtual elimination of MTCT (eMTCT) cont’d: Elimination will mean that MTCT transmission at 18-24 month of below 5%. UN recommends a comprehensive four pronged approach where elimination targets for each prong have been established. These include: - Prong 1; A 50% reduction of HIV incidence among women - Prong 2; Reduction of unmet need of family planning to zero among all women - Prong 3: -reaching over 90% of HIV positive women with More efficacious ARVs to reduce vertical transmission rate to <5% - Prong 4: -90% reduction of HIV related maternal deaths up to 12 months post-partum and 90% reduction in HIV attributable deaths among infants and children<5 years. Antenatal Care and Prevention of MTCT of HIV All pregnant women of unknown HIV status should be offered opt-out testing at the first ANC visit. Repeat HIV testing (After 3 months) in the third trimester should be offered to all women whose first antenatal test was performed before 28 weeks gestation. Women who decline HIV testing at the first antenatal visit should have follow up counseling at subsequent visits, and offered HIV testing. Women presenting in labor without documented HIV testing should have opt-out testing done urgently. All facilities providing antenatal and maternity care must have capability for providing HIV testing at all hours of operation. Postnatal HIV counseling and testing should be offered to all women with unknown HIV status A rapid HIV testing Algorithm for serial testing. . Pre-Test Education And/or Counseling First HIV Rapid Test - DETERMINE Negative Test Result – Counsel for Negative Result Positive test Result Second HIV Rapid Test - UNIGOLD Positive Test Result – Counsel for Positive Result Negative Test Result Third HIV test – Long ELISA Positive Test Result – Counsel for Positive Result Negative Test Result – Counsel for Negative Result Intra-partum Care Intra-partum care is the management of women from the onset of labour to delivery. a) Optimal Intra-partum Care The following guidelines should be followed for all women admitted to labour and delivery units • Minimize vaginal examinations. • Use aseptic techniques in conducting delivery. • Avoid routine artificial rupture of membranes (ARM). • Avoid prolonged labour by use of a partograph. • Minimize the risk of postpartum haemorrhage. • Use safe blood transfusion practices. Intra-partum Care cont’d: b) Specific Management of HIV Positive Pregnant Women Prophylactic Antiretroviral therapies: The ARV prophylactic regimen depends on whether the mother had ARVs during pregnancy or not. Thus, the health care worker should establish the regimen used during the ANC, whether the woman had taken ARVs at the onset of labour and determine the appropriate intra-partum ARV care as follows: Specific Management of HIV Positive Pregnant Women cont’d: i) No ARVs taken in pregnancy Mother in early labour (up to 1 hour before delivery) Mother: Intra-partum period; Give mother SdNVP 200mg at onset of labour+ AZT 600mg OR AZT 300mg BD + 3TC 150mg BD in labour and delivery Postpartum: Give mother AZT 300mg and 3TC 150mg BD for 7days. Assess for ART eligibility and initiate HAART as indicated Infant: Breastfeeding infant Daily NVP from birth until one week after all exposure to breast milk has ended Non-breastfeeding infant NVP for 6 weeks Specific Management of HIV Positive Pregnant Women cont’d: ii)Mother received HAART in Pregnancy • Regardless of duration received HAART (Applies to both women taking ART and Option B plus) • Continue the HAART regimen through labour and delivery and post partum period • Give infant Nevirapine syrup as above • Link the mother baby pair to chronic HIV care in the post partum period Specific Management of HIV Positive Pregnant Women cont’d: iii)Mother received AZT 300mg BD in Pregnancy Mother: Intra-partum and post-partum period regimen are same as above Infant Breastfeeding infant: - Daily NVP from birth until one week after all exposure to breast milk has ended Non-breastfeeding infant - NVP for 6 weeks Specific Management of HIV Positive Pregnant Women cont’d: iv) Mother received HAART in Pregnancy Regardless of duration received HAART (Applies to both women taking ART and Option B plus) Continue the HAART regimen through labour and delivery and post partum period Give infant Nevirapine syrup as above Link the mother baby pair to chronic HIV care in the post partum period Intra-partum Care cont’d: c) Mode of delivery - Elective caesarean section (CS) reduces the risk of HIV MTCT as compared to vaginal delivery if the viral load is >1000 copies per ml, but may not be available in many settings - Where CS is performed (elective or emergency) in HIV positive women, prophylactic antibiotics should be administered - If the CS is performed after prolonged labour or rupture of membranes, full courses of antibiotics should be prescribed. Use of Antiretroviral Drugs in Pregnancy for HIV Treatment and Prevention of Mother-to-Child Transmission of HIV Infection All HIV-infected pregnant women should be counseled on comprehensive HIV care including use of ARVs for their own health and for PMTCT. All HIV-infected pregnant women should have their HIV disease staged using: - WHO clinical staging (see Appendix 2) and - Immunological staging (CD4 count) The women should also be screened and treated for opportunistic infections (OIs) including Tuberculosis (TB). All HIV-infected pregnant women should have baseline laboratory and other necessary diagnostic evaluations. These should include: Routine antenatal care laboratory investigations that are normally done for all pregnant women (haemoglobin, H.b, rhesus blood group and ABO typing, VDRL, urine analysis and screening for STI). ALT and creatinine levels for women eligible for HAART. ARV use: ARVs are used for treating HIV-infected eligible women and/or for prevention of mother-to-child transmission. ARVs for Treatment (ART) & for PMTCT: - HIV-infected pregnant women eligible for ART should initiate ART as soon as possible (after adherence counselling) - HIV-infected pregnant women already on ART before becoming pregnant should continue ART. - Regimen substitution may be necessary in some cases - Evaluation for treatment response/failure should be done as soon as feasible ARV use cont’d: ARVs for prophylaxis (PMTCT): - Mothers who are not eligible for ART (women needing ARV prophylaxis) should be started on ARV prophylaxis. - They should be initiated on AZT (300 mg BD) from 14 weeks of pregnancy or as soon as possible thereafter - At the onset of labour, give AZT 600 mg PLUS 3TC 300 mg PLUS NVP 200 mg at once followed by AZT (300 mg BD) and 3TC (150 mg BD) should be for seven days post-delivery. - Single dose NVP given at the beginning of labour has the ability to rapidly decrease intracellular and extracellular HIV viral levels and to act synergistically with AZT and 3TC. - However, to reduce the risk of development of NVP resistance following sd-NVP, a 7-day post partum regimen of AZT and 3TC is given to the mother after delivery. This is called OPTION A of ARV prophylaxis ARV use cont’d: However, in settings with the capacity to initiate and monitor triple therapy on HIV infected pregnant women, triple ARV prophylaxis can be used. This is called OPTION B. When continued for life without interruption, it’s called OPTION B PLUS. Due to the risk of NVP-associated hepatic toxicity in women with a CD4 count >250 cells/mm, it may be necessary to use LPV/r-based triple therapy. Emerging evidence has shown increased morbidity and mortality in patients who interrupt ART hence women who are initiated on triple ARV prophylaxis for PMTCT should continue with lifelong therapy irrespective of CD4 count or WHO clinical stage or breastfeeding status. Criteria for initiating ARV treatment (ART) in pregnant women based on clinical stage and availability of CD4 Count WHO Clinical Stage CD4 testing not available CD4 testing available 1 Do not Treat ART if CD4≤350 cells /mm3 2 Do not Treat ART if CD4 ≤ 350 cells /mm3 3 Treat ART irrespective of CD4 count. (Consider CD4 values for better management) 4 ART irrespective of CD4 cell count Recommended first-line ART regimen for treating pregnant women and prophylactic regimen for infants First line ART regimen for women Nevirapine exposure within 12 months Nevirapine exposure >12 months ago OR No Nevirapine exposure Preferred AZT + 3TC+ LPV/r Alternative TDF + 3TC + LPV/r Preferred AZT + 3TC + NVP/EFV* Alternative TDF + 3TC + NVP/EFV* *EFV should not be used in first 8 weeks (1st trimester) of pregnancy and should be changed to NVP if in 1st trimester of pregnant. - 2 NRTIs (AZT and 3TC) acting as a “treatment backbone”, with addition of an NNRTI (NVP) remains the preferred first-line ARV therapy in resource-poor settings - Protease inhibitors based regimens are preferable when CD4 count is higher than 250 **EFV may be used instead of NVP after first trimester Management of HIV and ARV options in Women with Anaemia Haemoglobin g/dL Grade Remarks 8 - 10 Mild Look for treatable causes and manage, Give haematinics irrespective of gestation 6-8 Moderate AZT contraindicated. Initiate ART irrespective of CD4 with TDF in place of AZT i.e. (TDF+3TC+NVP/EFV). Transfuse if >36 weeks gestation and if <36 weeks gestation give haematinics 6 Severe AZT contraindicated. Initiate ART irrespective of CD4 with TDF in place of AZT i.e. (TDF+3TC+NVP/EFV). Transfuse irrespective of gestation Notes: Important considerations that modify choice of ARVs during pregnancy include CD4 count, maternal anaemia and stage of pregnancy OPTION B Plus: Alternative Maternal triple ARV prophylaxis to prevent MTCT In line with the national PMTCT goal to achieve virtual elimination of MTCT of HIV by 2015, facilities with ability to initiate and monitor patients on HAART will be encouraged to initiate triple ARVs (HAART) for life(uninterrupted) on all HIV positive pregnant mothers regardless of their WHO clinical stage or CD4 count in order to attain maximal viral load suppression WHO staging and CD4 testing is recommended at baseline to monitor progress. Infants born to mothers on HAART would be put on daily NVP for 6 weeks regardless of feeding option. These mothers should be enrolled for chronic care and monitored accordingly. OPTION B Plus: Alternative Maternal triple ARV prophylaxis to prevent MTCT cont’d: The provision of maternal triple ARV prophylaxis during pregnancy in women who are not eligible for ART results in very low Utero and peripartum transmission rates. A high value is also placed on the simplicity of the intervention as it contains only one maternal and one infant regimen and may be available as a once daily fixed dose combination. The recommended maternal triple ARV regimens for option B plus include TDF+3TC+EFV, AZT+3TC+EFV, AZT+3TC+LPV/r, AZT+3TC+ABC. Nevirapine based regimens are not recommended because of the risk of hepatotoxicity for women with high CD4 counts(>250 cells/mm). Why option B plus and not Option B Emerging evidence show that Non ART eligible women started of Triple ART followed by interruption leads to deterioration with morbidity and mortality* Other evidence suggests that most women Not eligible for ART during pregnancy will become eligible anyway within a period of 2 years. Benefits of option B plus: For regimen simplicity. No Staging or CD4 testing. (Although CD4 counts or viral load assays are still desirable for determining baseline immunological status and monitoring) Extended protection from mother-to-child transmission in future pregnancies from conception A strong and continuing prevention benefit against sexual transmission in sero-discordant couples and partners likely benefit to the woman’s health of earlier treatment and avoiding the risks of stopping and starting triple ARVs, especially in settings with high fertility. Infant Nevirapine Prophylaxis for HIV Exposed Infants Age Nevirapine Dose 0 – 6 weeks Birth weight < 2500 g – 10 mg (1 ml) once daily Birth weight > 2500 g – 15 mg (1.5 ml) once daily 6 weeks – 14 weeks 20 mg ( 2 ml) once daily 14 weeks to 6 months 25 mg (2.5 ml) once daily 6 months – 9 months 30 mg (3 ml) once daily 9 months – 12 months 40 mg (4 ml) once daily > 12 months 50 mg (5 ml) once daily NOTE: • AZT 15mg/kg twice daily is an alternative for infants on TB treatment or NVP toxicity • 3TC is an alternative for infants with severe NVP toxicity (grade 3 or 4)/or if baby is on TB treatment with rifampicin containing regimen Infant Lamivudine prophylaxis for infants who cannot take NVP Age Dosage 0-4weeks 2mg/kg twice daily >4 weeks 4mg/kg twice daily Infant AZT prophylaxis dosage for HIV exposed infants Birth weight Dosage <2500g 10mg/kg twice a day >2500g 15mg/kg twice a day Immediate Postnatal and Neonatal Care Immediate postnatal and neonatal care refers to the package of services provided to the mother and infant before they leave the health facility (up to 48 hours) after delivery. The period provides an opportunity to educate all mothers on optimal postnatal care including HIV, to provide HIV counselling and testing if it was not done previously, and to reinforce the education provided during the antenatal period. Both HIV infected and HIV uninfected mothers should receive this education and counselling before discharge. Immediate Postnatal and Neonatal Care cont’d: The following guidelines should be followed for all women and infants in the immediate post partum period: a) Optimal postpartum care Support infant feeding options. For all HIV negative women, women of unknown HIV status and HIV positive mothers opting for exclusive breastfeeding, initiate breastfeeding within half hour of birth and follow other guidelines as per Baby Friendly Hospital Initiative (BFHI). Package of services provided to mothers and neonates within first 48 hours after delivery Services targeting HIV infected and HIV uninfected mothers would include: Health education on maternal nutrition; Advice on danger signs (mother and newborn), emergency preparedness and follow up; care of the newborn Following the standard guidelines on the care of a newborn Immediate Postnatal and Neonatal Care cont’d: Optimal postpartum care cont’d: Identification of complications in mother and newborn - manage and/or refer appropriately Routine postpartum care: blood pressure measurement; breast examination; examination of the uterus, the perineum and lochia. Ensure regular passage of urine and proper hygiene to prevent infection; checking for signs of anaemia, fever and tachycardia and Vitamin A supplementation Establish the HIV status of all postnatal mothers including those who delivered outside the health institution setting; Provide HIV testing and counselling for mothers with unknown HIV status and all those who tested negative and did not get re-tested in the antenatal period; Encourage HIV results disclosure and partner testing. All babies should receive their routine immunization (OPV and BCG) in their first hours of life. Immediate Postnatal and Neonatal Care cont’d: b) Specific postpartum care for HIV positive women: Support exclusive breastfeeding (with cover of ARVs) until six months unless the mother has been counseled on replacement feeding and meets the AFASS criteria. Initiate/continue Cotrimoxazole for all HIV positive women For the newly diagnosed, perform WHO Staging, CD4 Count and treat/refer for ART appropriately. For mothers on ART/HAART; continue with treatment Immediate Postnatal and Neonatal Care cont’d: c) Specific care for HIV exposed infants: Initiate Nevirapine syrup prophylaxis Counsel/provide infant feeding options Late Postnatal Care and Family Planning Late postnatal care is provided to the mother and the child 48 hours to 6 weeks after delivery. During this period, the health of the mother and child is assessed and closely monitored. The risk of MTCT during the postpartum period can be reduced by providing HIV counselling and testing, ARV prophylaxis to the mother or exposed babies, counselling on appropriate infant feeding options and breast care. Postpartum care for HIV positive women should include clinical staging, CD4 count and ART for those who qualify. Family planning services are among the core interventions of PMTCT provided to help women determine future childbearing patterns including the prevention of HIV-infected births. Reproductive health counselling can help a woman practice safer sex and determine her future childbearing patterns on a more responsible and informed basis Optimal postpartum care for all women This entails routine postpartum care including; Breast examination, examination of the uterus, examination of the perineum and lochia, passage of urine regularly, proper hygiene to prevent infection, checking for signs of anemia, fever and tachycardia and advice on doing perineal exercises. Counselling and testing for mothers of unknown HIV status and for those who tested negative during early antenatal period. Counselling on maternal nutrition; infant feeding options, risk reduction; hygiene, breast care and dual protection Provision of condoms and initiation of viable method of contraception; Routine postpartum care cont’d: - Screening for STI s and Cancer of the Cervix at 4-6 weeks - Counselling on post-partum danger signs in the mother and appropriate action - Counselling on avoidance of penetrative sex until there is no lochia. - Counselling on Malaria prevention - Care and support for the mother – partner support and linkage to psychosocial support groups - Initiation of care and treatments as per national ART guidelines. Optimal postpartum care for HIV positive women i) Breast care in breastfeeding mothers: Should wear a good supporting brassiere day and night. Whenever breasts are engorged, ask the mother to express to comfortable level (not emptying breast). Give analgesics for pain. Initiate contraception within 4 weeks of delivery Optimal postpartum care for HIV positive women ii) Lochia: Put emphasis on good perineal hygiene and proper handling of body fluids. Avoid contaminating the baby with body fluids or with bedding soiled with lochia. Sharing of beds by mothers in the hospital should be discouraged. Optimal postpartum care for HIV positive women cont’d: iii) Caesarean Section: - Broad spectrum antibiotics should be used routinely after CS. Essential maternal education and follow-up: Monitor for breast and pelvic infection at all post natal clinic visits. Educate on prompt health seeking behaviour. Health education on hygiene, lochia and breast care. Avoid sexual intercourse for at least 2 weeks after birth or until there is no longer any lochia rubra or serosa. Do pap smear or VIA at 4-6 weeks. For every sexual activity, the couple should use condoms. Optimal postpartum care for HIV positive women cont’d: Contraception Persons living with HIV and AIDS have been shown to have a higher (over 50%, KAIS 2007) unmet FP need as the non-infected (26%, KDHS 2008/9)) persons. FP service providers must ensure that safe and effective contraception is accessible to women who are HIV positive in order to help them not only plan their future child bearing patterns but also to prevent the births of HIV positive children. All mothers, regardless of their HIV status, have a right to receive adequate information on available methods of family planning and to make an informed choice on what is best for them. Contraception cont’d: With very few exceptions, all methods of contraception can be used by HIV positive women based on standard medical eligibility criteria including taking care of drug interactions All FP clients regardless of their status, should receive counseling about dual protection including Dual method use with emphasis on the importance of correct and consistent use of condoms Contraception cont’d: Lactational Amenorrhoea Method (LAM): - Suitable for exclusively breastfeeding HIV infected women who have not resumed menses - For HIV positive women, dual method contraception is advised. Contraception cont’d: Hormonal contraception: - All hormonal contraceptives can be used in HIV positive women including those on HAART. - Combined oral contraceptives may be contraindicated for use with drugs that induce hepatic micro-enzyme that may reduce the effectiveness of hormonal contraceptives: Included in this group, are some anti-TBs, some antiretrovirals, antifungals and anti-epileptics, and in conditions that cause malabsorption. Contraception cont’d: Intra-uterine contraceptive devices (IUCDs): - IUCDs are not contraindicated in HIV positive women. - In severely immuno-suppresed women, IUCD use should not be discontinued but new insertion is discouraged as it may be associated with increased risk of infection during the insertion process. - However, the IUCD may be inserted once the client is put on ARVs and is doing well on them Contraception cont’d: Surgical methods: - Surgical contraception should be offered to HIV positive women and their partners. Barrier methods: - Female and male condoms provide protection against STIs and reduce the risk of HIV transmission and should be encouraged alone or preferably used together with other more effective contraceptive methods to what is referred as Dual method use Contraception cont’d: Emergency contraception: - EC is a safe and effective way to prevent pregnancy after unprotected intercourse. - It can be started up to five days (120 hours) after unprotected intercourse. - should not be used as a regular contraceptive method. - can be used by HIV positive women. - HIV positive women should be informed about emergency contraception, where it is available, how to access and use it. Contraception cont’d: Fertility Awareness Based method: - Women who are HIV-positive who may or may not have AIDS and those on ARV therapy can use FAB methods without restrictions - women who want to use the Standard Days Method or Calendar method should have regular menstrual cycles - Women and couples relying on FAB methods should be counseled that they are not protected from STI and HIV transmission and should be encouraged to use condoms even on days when risk of pregnancy is low. Care, support and treatment for HIV positive mother and child HIV-positive mothers require care and support which includes: • Counselling. • OI prophylaxis and treatment. • Link to support groups and assessment of the need for ART. • Early infant diagnosis (EID) should be provided at six weeks and thereafter using EID algorithm Thank You! HIV Diagnosis in Children - Early infant diagnosis (EID) refers to the making of HIV diagnosis in infants and young children before 18 months of age. - EID gives an opportunity for early identification of HIV exposed and infected infants (due to suboptimal PMTCT service or lack of it) - early linkage to prevention for the exposed and care and treatment for the infected - disease progression in HIV infected infants is fast, with a high mortality rate (> 50%) by 2 years of age. HIV Diagnosis in Children cont’d: - HIV antibody testing among children aged 18 months or more is able to determine whether a child is infected or not - During pregnancy, there is transplacental transfer of HIV antibodies to the unborn baby from the mother, these antibodies disappear with time from the infant’s blood. - Antibody testing in children aged less than18 months identifies children who have been exposed to their mothers’ HIV infection or who may be truly infected and are making HIV antibodies. HIV Diagnosis in Children cont’d: - Currently, there is no test to differentiate the mother’s antibodies from those produced by the baby. - In order to identify the HIV-infected child aged less than 18 months, a second test is required for all babies testing positive on antibody testing or known to be HIVexposed (mother is HIV-positive). - Infant DNA (or RNA) PCR testing is the current recommended method for EID. HIV Diagnosis in Children cont’d: - Since most babies loose maternal antibodies (Ab) by 9 months, a negative antibody test will identify uninfected babies as long as they are not breastfeeding - A positive antibody test at >9 months, although highly likely to be diagnostic, may still be due to passively carried maternal antibodies - A confirmatory PCR test should be done for all positive antibody tests before 18 months of age. - An antibody test at /after 18 months of age is confirmatory of HIV infection in HIV exposed infants. Guidelines for HIV diagnosis in children • Perform routine rapid HIV antibody tests for all mothers or infants presenting with unknown HIV status to establish exposure status of the infants. • Perform routine dry blood spots (DBS) for DNA PCR for all infants known to be HIV-exposed at 6 weeks or at first contact thereafter • Perform routine antibody testing for all sick infants in outpatient and paediatric wards to establish HIV exposure/infection status. • Perform a confirmatory DNA, PCR test for all HIV-exposed sick infants with a positive antibody test before 18 months of age. • All HIV-exposed infants should be started on co-trimoxazole from 6 weeks of age or on first contact thereafter. HIV negative infant at age 6 weeks or first contact • Perform antibody testing at 9 months and 18 months of age. • If HIV negative at 9 months and still breastfeeding, continue cotrimoxazole and repeat Ab test at 2 months after cessation of breastfeeding or at 18 months whichever comes first. • If HIV antibody test is positive before 18 months perform a confirmatory DNA PCR test. • If NOT breastfeeding for at least 2 months and HIV test is negative, stop co-trimoxazole. • Perform confirmatory antibody testing at 18 months. HIV positive infant by DNA PCR • All HIV-positive infants should be started on HAART , regardless of their WHO stage , CD4 count or CD4%. • However, WHO clinical staging and CD4 count/percentage should be done for all HIV positive infants as a baseline. • All HIV-positive infants should have a visible guardian or care-taker before they can be started on ART to assure adherence. • All HIV positive infants should be started on Cotrimoxazole from 6 weeks or on first contact thereafter. • Breastfeeding should be encouraged for all infants who test HIV-positive for a minimum of one year. All HIV positive infants should be started on HAART regardless of WHO stage or CD4 count or %. Comprehensive care for HIV-exposed children: Both HIV-infected and uninfected children require comprehensive care Feeding Infants and Young Children Born to HIV Infected Mothers Transmission of HIV through Breastfeeding In Africa, 3 to 4 out of every 10 infants born to HIV infected women acquire HIV infection. Use of ARVS either for the mother or the infant significantly reduces the risk of HIV transmission from the mother to the child Exclusive replacement feeding if done appropriately reduces the risk of HIV transmission but hygiene should be observed to avoid the morbidity and mortality associated with it. Feeding options for a HIV exposed infant 1. Exclusive breastfeeding with ARVS 2. Exclusive Replacement feeding Operational Guidelines on Infant feeding (0-6 months) - All mothers who are HIV negative or are of unknown HIV status should be encouraged and supported to exclusively breastfeed for the first 6 months and continue breastfeeding with appropriate complementary feeding introduced thereafter. - All HIV positive mothers should be given information on available infant feeding options and counseled using recent scientific information on benefits and challenges for each option in order to help them make an informed choice. Operational Guidelines on Infant feeding (0-6 months) cont’d: - All HIV positive mothers who choose to breastfeed should be encouraged and supported to exclusively breastfeed for the first 6 months and continue breastfeeding up to 1 year with appropriate complementary feeds. Infants of these mothers should be provided with nevirapine prophylaxis for up to 1 week after complete cessation of breastfeeding. Operational Guidelines on Infant feeding (0-6 months) cont’d: - HIV positive mothers who choose not to breastfeed and meet AFASS criteria should be encouraged and supported to do exclusive replacement feeding for the first six months and appropriate complementary feeding introduced thereafter. Infants of these mothers should be provided with nevirapine prophylaxis for 6 weeks. Operational Guidelines on Infant feeding (0-6 months) cont’d: - In special circumstances determined by clinicians involving infants who cannot breastfeed e.g. orphans or abandoned babies or where the mother has conditions like mastitis preventing breastfeeding, the infant should be provided with exclusive replacement feeding with appropriate complementary feeds introduced thereafter. Operational Guidelines on Feeding Children 6 months and older - Complementary foods should be introduced with continued breastfeeding or with replacement feeding until a nutritionally adequate diet can be sustained without milk. - For HIV exposed infants, continued ARVs for the infants should be provided up to complete cessation of breastfeeding. - Abrupt cessation of breastfeeding is NO longer recommended as this causes psychological trauma for both the mother and the baby. - From 6 months animal milk can be introduced and should continue as an important component of the child’s diet. - Complementary foods should be prepared from locally available family foods. Nutritional Care and Support of HIV infected children Energy needs for asymptomatic HIV infected children increase by 10 percent to maintain growth as compared to the non-infected children while for symptomatic HIV infected child this increases by 50-100% There is no evidence of increased protein requirements. The requirements should be based on individual symptoms and needs. Micronutrient requirements do not change. Extracts from Research on Infant Feeding and HIV/AIDS Evidence available from current research data shows that: • Increased risk of mortality with replacement feeding is significant. • HIV free survival rate at 18 months of age does not significantly vary between an exclusively breastfed and exclusively replacement fed child. • Modified animal’s milk is no longer recommended for children less than 6 months of age. • Abrupt cessation of breastfeeding is no longer recommended. • Therefore, exclusive breastfeeding (With ARVs) up to 6 months is recommended unless a mother chooses replacement feeding and can meet AFASS criteria. • If breastfed infant is given solid foods (Mixed fed) before 6 months, the risk of HIV infection is eleven times as high as the exclusively breastfed infant. Care and Follow-up of Children of HIV-infected Mothers The following guidelines should be followed in the care and follow-up of children of HIV-infected mothers: - All HIV exposed infants should be seen in the health care facility within two weeks of delivery. - For all HIV exposed infants, monthly follow up visits are recommended beginning at six weeks through 2 years. - Where possible, visits should be linked to the immunisation and growth monitoring visits. - All HIV exposed infants should be started on co-trimoxazole prophylaxis from 6 weeks of age. Care and Follow-up of Children of HIV-infected Mothers cont’d: For infants who test HIV negative: - If they have stopped breastfeeding for 2 months or more, stop co-trimoxazole - If still breastfeeding, confirm status after stopping breastfeeding. Co-trimoxazole should be continued until two months after complete cessation of breastfeeding. For infants who test HIV positive by DNA PCR before 18 months or by antibody test after 18 months of age, co-trimoxazole should be given daily for life.
