Indiana HIV Outbreak: CDC Study of Cases Shows Most are the Same Strain

A genetic analysis of HIV samples taken from about half the people infected in the largest HIV outbreak in Indiana history shows nearly all of them have the same strain of the virus, a finding one health expert says is a sobering reminder of how rapidly HIV can spread among intravenous drug users.
Indiana’s state epidemiologist, Pam Pontones, cautioned the findings by the Centers for Disease Control and Prevention are “very preliminary”. But she said they suggest that the HIV strain detected in southeastern Indiana’s outbreak was introduced there during the past six to 12 months.
