About BAIS V

The Botswana HIV/AIDS Impact Survey V, or BAIS V, is a national survey assessing the prevalence of HIV and the coverage and impact of HIV services, as well as characterizing HIV-related risk behaviors, using a nationally representative sample of children aged 6 weeks to 14 years and adults aged 15 years to 64 years. BAIS V is the fifth such survey performed in Botswana. This PEPFAR-funded survey will reach approximately 13,500 randomly selected households and interview 28,800 people.

BAIS V will help the Government of Botswana, its partners, and the public know how many people are currently infected with HIV, how many people have new infections, and how many people living with HIV are on effective treatment.


Benefits of BAIS V

  • Botswana is among several countries in sub-Saharan Africa and the Caribbean to conduct this type of survey, which will inform funding priorities for national, sub-national, and global HIV programming.

Frequently Asked Questions

The Fifth Botswana HIV/AIDS Impact Survey (BAIS V) is an initiative to measure the reach and impact of HIV programs in the country.

It is a household-based survey covering randomly selected households countrywide. Information collected by BAIS V team will help the government, its partners, and the public know how many people are currently infected with HIV (HIV prevalence), how many people have new infections (HIV incidence), and how many people with HIV are on effective treatment (HIV viral load suppression).

The Government of Botswana (GOB) is leading the BAIS V in collaboration with other partners. The survey is supported by the United States President’s Emergency Plan for AIDS Relief (PEPFAR) with technical support from the National AIDS and Health Promotion Agency (NAHPA), Ministry of Health and Wellness (MOHW), Statistics Botswana, the U.S. Centers for Disease Control and Prevention (CDC), and the University of Maryland, Baltimore (UMB).

The survey will involve about 14,000 randomly selected households throughout the country. This means that all households in Botswana have an equal chance to be randomly selected to be part of the survey. Overall, approximately 29,000 people will be part of the survey.

Only households that are selected can be part of the survey. If your household is selected, only persons who are aged 6 weeks to 64 years in the household can take part in the survey.
