We are facing a situation where every Motswana is either infected or affected; having lost a relative, friend, workmate “Batswana, letsema le thata ka mong wa lona!” or an acquaintance to the pandemic. For Botswana, factors that drive the epidemic are multiple, intertwined and com- Ntwa e bolotse! plex and these have social-cultural and economic antecedents. In realizing the complexity and magnitude of the disease, Government has shown an unprecedented high level of political and economic commitment to its control by declaring war against it, and adopting a multi-sectoral approach. Coupled with this was a call to the international community to assist and this has resulted in tremendous response in the form of funding and technical support. Festus G. Mogae President of the Republic of Botswana Locally, the private sector, civil societies including people liv- (Chairman, National AIDS Council) ing with HIV/AIDS (PLWA) organizations, have risen to the November, 2003 occasion to form a partnership with government in fighting the epidemic. The national response has resulted in setting up prevention programs such as behavior change and com- munication, Voluntary Counseling and Testing, STI Control and prevention of mother to child transmission (PMTCT). Care and support programs have been scaled up to include public provision of Highly Active Antiretroviral Therapy (HAART) and Community Home Based Care Programs. Impact mitigation and reduction in stigma have been addressed at all levels by providing funding for income generating activities, support for orphans and vulnerable children, and greater involvement of PLWA in the national response. i National AIDS Coordinating Agency (NACA) in collaboration with AIDS/STD Unit, the BOTUSA Project (CDC), District Health Teams, the Botswana Harvard Partnership and WHO Botswana 2003 Second Generation HIV Surveillance Report ii National AIDS Coordinating Agency (NACA) in collaboration with AIDS/STD Unit, the BOTUSA Project (CDC), District Health Teams, the Botswana Harvard Partnership and WHO Botswana 2003 Second Generation HIV Surveillance Report PREFACE in 2002, which currently has enrolled 9228 patients out of IV/AIDS is spreading relentlessly worldwide the estimated 110 000 living with AIDS.

A disturbing trend however is emerging where rural prevalence is on the increase while urban prevalence is stabilizing.

Minister of Health Vice Chairperson, National AIDS Council The high prevalence is coupled with an increased number of AIDS, TB and Genital Herpes cases and other AIDS-relat- ed illnesses. The result has been a huge burden in a limited resource health care system, with increased bed occupancy rates to over 100% in most medical wards and increased average length of stay to over 14 days for medical patients over the years. However, this trend is expected to reverse with the introduction of anti retroviral treatment provision iii National AIDS Coordinating Agency (NACA) in collaboration with AIDS/STD Unit, the BOTUSA Project (CDC), District Health Teams, the Botswana Harvard Partnership and WHO Botswana 2003 Second Generation HIV Surveillance Report iv National AIDS Coordinating Agency (NACA) in collaboration with AIDS/STD Unit, the BOTUSA Project (CDC), District Health Teams, the Botswana Harvard Partnership and WHO Botswana 2003 Second Generation HIV Surveillance Report ACKNOWLEDGMENTS Finally I would like to extend my sincere gratitude to all the he National AIDS Coordinating Agency in col- staff of National AIDS Coordinating Agency, the Ministry of laboration with the Ministry of Health, Health, Ministry of Local government, CSO staff and the AIDS/STD Unit, Ministry of Local Government, Data Management Team for the commitment and dedica- Central Statistics Office and all the district tion they have placed in making this document a success. teams would like to pass their sincere gratitude Tto all those who contributed in making the 2003 Second Generation HIV surveillance a success.
