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

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

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.

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.

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)

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.

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

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.

- 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

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.

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

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:

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.

 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.
