The incidence of Kaposi sarcoma among injection drug users with AIDS in the United States

Increased prevalence of human herpesvirus 8 (HHV-8), the causative agent of Kaposi sarcoma (KS) were reported, among injection drugs users (IDUs), suggesting the HHV-8 may be transmitted through blood-borne or other exposures common in the population. Data from a large US registry-based cohort of individuals with AIDs is used to compare the incidence of AIDS-associated KS in IDUs to that in non-IDUs.
