HIV/AIDS epidemiological surveillance for the WHO African Region

2003 update


23 September 2003

ISBN 92-9023-100-9

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 as a whole, and by sub-region. Volume II consists of country profiles that include brief descriptions of the recent data and trends, with a focus on young people.

The report does not provide HIV/AIDS estimates, but presents a synthesis and analysis of data generated by the existing surveillance systems. National estimates of HIV prevalence and numbers of people HIV infected will be made by countries in close collaboration with UNAIDS and WHO at the end of 2003.

This analysis of the epidemiological situation based on the most recent data from all countries in the WHO African Region is intended to provide information for national Ministries of Health and all in-country stakeholders, United Nations agencies, and international development partners. The information contained in the reports will be useful as a technical support tool for advocacy, and will contribute to the planning of interventions for HIV/AIDS and the prevention and care of STIs, and presents an intermediate assessment of the status of surveillance systems in countries.
