DAMAX was contracted to support UNHCR conduct a survey to determine HIV prevalence and associated factors of HIV infection among the refugee population aged 15-49, estimate HIV prevalence among adults 15-49 years and identify risk factors associated with HIV and other sexually transmitted infections, especially syphilis and Hepatitis B among the refugee population. The survey also assessed the coverage of HIV-related services, including HIV counseling and Testing (HCT), PMTCT, knowledge of HIV status, coverage of care and treatment services in the region, and estimate HIV incidence and level of viral load suppression among adult refugees in the camps. The Ministry of Home Affairs in Tanzania has been working closely with UNHCR to support and host around 200,000 refugees as of early 2022. Most refugees come from Burundi and the Democratic Republic of the Congo, and more than 80 percent are hosted in the Kigoma region, Nyarugusu and Nduta refugee camps in Kasulu and Kibondo districts (United Republic of Tanzania, n.d.). DAMAX managed to reach 1008 households in Nyarugusu and Nduta refugee camps, Kigoma.
