This project will first increase the accessibility and acceptability of rapid HIV testing in health clinics located in or near four low-income communities in San Salvador, El Salvador. The investigators will use crack users' social networks and small incentives, as recommended by the CDC, in collaboration with the Salvadoran Ministry of Public Health and Social Assistance (MSPAS) to encourage crack users to receive HIV testing. The second part of the intervention consists of training 8 Peer Leaders to recruit and lead a Peer Network Intervention among 400 crack users to change norms supporting HIV protective behaviors. The intervention will include monthly meetings open to crack using and non-crack using community residents to reinforce HIV risk reduction skills, and discussion of other topics related to HIV such as illicit drug use and interpersonal violence and community-wide HIV awareness events. Our hypothesis is that these two intervention features will singly, and in combination, reduce HIV risk behaviors among Salvadoran crack users.

Primary purpose prevention
Participants in this arm will be recruited through social networks and will receive an HIV test.
social network hiv testing

Eight (8) current or former crack users will be recruited to facilitate small networks of crack users in a three-day intervention. They will also facilitate monthly meetings open to all community members regarding HIV prevention and interpersonal violence.
peer network intervention
Peer leaders will recruit small networks of crack users and facilitate a three-day prevention intervention.
