Our study will be recruiting youth between the ages of 12 and 24 years with newly diagnosed HIV infection (Acute /Recent or Established HIV). The study is open to all patients within this age group with a new diagnosis of HIV infection, including pregnant women. This study will include adolescents who are displaced and living in shelters or in the streets. These homeless youth will include African American Gay, Bisexual, and Transgendered Youth (GBTY), who are very susceptible to substance abuse, juvenile justice contact, and acquisition of HIV and other sexually transmitted infections (STI).
