The prevalence of HIV-1 infection has reached an alarming level among IDUs in Tehran, with incarceration-related exposures revealed to be the main correlates of HIV-1 infection.

HIV-1 infection is already prevalent among drug users in Tehran, Iran and shared injection inside prison has been revealed to be a particular risk factor for HIV-1 infection among injecting drug users. Harm reduction programs which have been started in Iran should be urgently expanded particularly in correctional settings and strengthened by condom use promotion to prevent sexual acquisition or transmission of HIV-1 among drug users.
