Ethiopia’s National AIDS Resource Center estimates that the 2013 infection rate is 1.3% and declining. In Addis Ababa, HIV/AIDS levels among prostitutes are thought to be close to 50 percent. The primary mode of HIV transmission in Ethiopia is heterosexual contact. Young women are more vulnerable to infection than young men; urban women are three times as likely to be infected as urban men, although in rural areas the difference between genders is negligible. Populations at higher risk for HIV infection include sex workers, truck drivers, police officers and members of the military. There is little IV drug use in Ethiopia.
