This
figure lists in rank order 50 countries that have the highest
estimated HIV prevalence rate in the 15-49 year old (most
sexually active)* population.
Over 70% of these countries are in sub-Saharan Africa (SSA)
and close to 20% are in the Caribbean region and just over 5% are in
Asia & Pacific region. In all
of these countries, (except Ukraine which is probably overestimated)
there has been extensive (NOT GENERALIZED) heterosexual HIV
transmission. Heterosexual
HIV transmission predominates in the Caribbean countries with high
HIV prevalence rates and in the three “high” prevalence
Asian-Pacific countries also.
It should be
noted that of the world total of over 160 countries, that more than 100
(more than two-thirds) have estimated national HIV prevalence levels less
than 1% and close to half of these latter countries have HIV prevalence
about 0.1% (1/1,000 of the 15-49 year old population) or less!

One of the most important contributions I made to HIV/AIDS
epidemiology when I was at GPA/WHO was to change the designation of
the 15-49 year old population from "the sexually active
age group" to "the most sexually active age
group." As an
epidemiologist broken down by age and sex (I did not join WHO until
I was 55) I could attest to the fact that persons after the age of
50 were still sexually active!
