HIV/AIDS epidemiological surveillance for the WHO African Region
The current report presents an update of the status of the
HIV/AIDS epidemic in the WHO African Region, based predominantly
on data from country surveillance reports produced for 2001 and
2002. Data from population-based surveys and selected research
studies are also included. The focus is on the assessment of
trends in HIV prevalence within countries and sub-regions. In
addition, data are presented on the current situation and trends
in STIs and sexual behaviour, which are both part of
comprehensive HIV surveillance systems (also called “second
generation” surveillance) (UNAIDS and WHO, 2000). Determinants
and risk factors for HIV infection are not addressed in this
report. The report limits itself to describing an
epidemiological situation analysis, which is essential for the
response, including HIV/AIDS treatment. The results are
presented in two parts. Volume I presents a comprehensive review
of the most recent data in the WHO African Region
