HIV incidence and recent injections among adults in rural southwestern Uganda

Thirty-six incident HIV cases were matched for age, sex and time period with 36 controls to examine associations with recent injections. A significant association between HIV incidence and a history of injections was detected that was not reduced after adjusting for available sexual behaviour variables. This association could either be the result of injections causing HIV infection or, more likely, injections for seroconversion illnesses or other consequences of unsafe sex.
