Global Epidemiology of HIV
• 40 million people world wide have HIV.
• 90% of the epidemic is concentrated in the
developing world.
• 90% of AIDS infected children and 70% of newly
diagnosed HIV infections are in sub-Saharan
Africa.
• 28 of the 40 million people with HIV are from
sub-Saharan Africa.
• Four decades of gains in life expectancy and infant
mortality have been lost due to HIV.
Gender Inequality
• Financial or material dependence on men
• Often women cannot control when, with whom
and in what circumstances they have sex
• Many women have to exchange sex for material
favors, for daily survival
• Domestic servitude

with forced sex among women in rural Haiti: implications for the
prevention of HIV and other STDs. Soc Sci & Med 2005;60(4):679689.
War, Displacement
Rwanda
• Of 250000 women who survived the
genocide, 70% are HIV positive
• 1 million orphans and vulnerable children,
many become servants or are forced into
prostitution
Childhood
Uganda
• 15% in 1991 to 4.1% in 2003 Nationally vs.
11.3% among HCW in 2001 in the district
of Gulu unchanged since 1998
• AIDS accounts for 69% of all deaths in the
Gulu area, a region of Northern Uganda

Work
Rural to Urban Movement
• Migration for work wave in rural
Africa
– Enclaves of migrant men with few female
partners and high levels of social isolation
– Work as domestic servants
• Recurrent of seasonal migrants bring
infection to village
2001 Durex Global Sex Survey
• 18 500 adults worldwide.
• 28 countries: (South Africa and Nigeria)
• Onset of sexual activity: Range: Americans 16Chinese 22.
• Average number of lifetime sexual partners:

It’s too hard…………2000
It's 17 to 25 pills a day...
Every two hours....
And you have to change
the cocktail …every
three or four months , or
you can die from the
toxicity of the drugs.
'Many people in Africa have never seen a clock or a
watch their entire lives. And if you say, one o'clock in
the afternoon, they do not know what you are talking
about.'

Adherence in Developing Countries
• Compares favorably to that reported in the
developed world (Senegal, South Africa)
• Provision of free therapy improves
adherence (Senegal, Botswana)
• Additional out of pocket costs to patients
serve as a deterrent to ART adherence

Prof
• Waiting lists for enrollment
• Errors in initiation and follow up
– Availability of trained personnel to
assess patients needing therapy
– Training focuses on “ART protocols”
but little practical
Health Systems
• User fees for service and
testing remain a barrier
• No functioning primary care
system to bring patients in
• Lack of basic tools and
supplies
Health
System
Community and Home Environment
• When basic necessities lacking
(food, shelter) ART becomes a
lower priority
• Long distances from clinic
• Lack of transportation fees
• Patients new to the medical

Accompagnateurs
• Selected by the patient needing treatment
• Visit patients at home once or twice daily; each
accompagnateur follows an average of 4 patients
• Monthy salary is 300 Haitian dollars ($38
American)
• Supervised by the head nurse, who regularly meets
with each patient and accompagnateur to discuss
medication adherence

The Team!
• Adding HIV/AIDS care and treatment
cannot be done without a investment in
health care workers.
• Public health clinics stand empty because
salaries are too low and working conditions
are unacceptable.

Expansion Successes
• Over 8000 HIV-positive people followed
• 1500 patients now being treated with
directly observed HAART (“DOTHAART”).
• 6 public health clinics are operational in
the central plateau now with 341000
ambulatory visits per year
Efficacy of ART in Resource-Poor
Settings
• ART treatment programs in resource-poor
settings have efficacy rates similar to those
reported in developed countries.
• The provision of medications free of charge
to the patient is associated with a
significantly increased probability of
virologic suppression at months 6 and 12 of
ART.
Ivers, L et al. CID 2005:41 (15 July)
Goals of Therapy….
• Suppression of viral
replication
• Recovery of CD4
cells
•Defense against
opportunistic
infections
•Decreased mortality
•Improved quality of
life
•Decreased
transmission

to get treatment, since we’re all
