PrevenSida is an innovative USAID project to support research and implementation to increase healthy behavior among key populations at higher risk of HIV infection and reduce HIV transmission by increasing condom use, access to counseling, HIV testing promotion, and reducing the number of sexual partners. 

Funded by PEPFAR, the project’s activities encompass five programmatic areas: strengthening institutional capacity of NGOs serving most at-risk populations (MARPs) and people living with HIV (PLHIV); improving access to and quality of HIV preventive services; reducing stigma and discrimination; improving the participation of NGOs representing MARPs and PLHIV in the HIV/AIDS national response; and improving the generation, dissemination, and use of HIV strategic information with key populations in Central America.  The project serves Guatemala, Honduras, El Salvador, Nicaragua, and Panama.

Key Activities

Regional Strategic Information: Based on the successful experience of Nicaragua, PrevenSida offers technical and financial support to other countries in Central America to develop research related to the access of key populations to the community-based care continuum cascade; determinants of health among key populations; logistics needs assessments for NGOs under the universal HIV treatment strategy; and characteristics of the HIV epidemic in sub-populations.

Institutional Strengthening/Quality Improvement: The project supports NGOs to train their staff in the continuum of care model using the care cascade as an exercise to analyze local gaps in care for people with HIV.

Continuum of Care: PrevenSida supports NGOs to deliver a core package of HIV combination prevention services, including counseling and testing by mobile teams, community-based clinical assessment, CD4 testing through a mobile unit, community-based psychological care for PLHIV and transgender persons, linkage to health care services, and community care to support retention in treatment and care.

Knowledge Management/Strategic Information. PrevenSida promotes knowledge transfer across NGOs, HIV prevention services beneficiaries, and the community.  The project also supports monthly electronic bulletins that disseminate best practices and applied research findings with public, private, academic institutions and civil society; collaborative learning sessions; and research dissemination forums in each country.
