Participants will be offered HIV and STI testing and counseling. Those with reactive HIV rapid test results will have HIV infection confirmed by Western blot and will have a CD4 cell count and viral load test performed. Counselors will provide post-test HIV participants counseling to those who have had HIV rapid test performed and will schedule all participants to return to the clinic approximately two weeks later to receive additional test results. The counselor will also discuss the participant's engagement in health care, and will determine the participant's health and other service needs. The counselor will also inquire about homophobic or partner violence and provide any care referrals if needed. Additionally, risk reduction counseling will be provided.
