Porn actor tests positive for HIV

LOS ANGELES

California public-health officials have issued an alert after finding “very strong evidence” that an adult film actor became infected with HIV as a result of unprotected sex on an out-of-state film shoot.

The Department of Public Health said Monday that the male actor tested positive for the virus that causes AIDS after engaging in unprotected sex with several other male actors during two separate film shoots. He had tested negative before the shoot.

“During the second film shoot, he had symptoms of a viral infection,” the alert states. “The actor went to a clinic and had another blood test that showed he recently had become infected with HIV.”

One actor from the second shoot has since tested positive for HIV. According to the health department, lab results indicate the first actor who tested positive “probably transmitted” HIV to the second.

A health department official was unable to immediately release further details regarding the lab testing and investigation. The alert notes that very early in an HIV infection, the test can be negative “even though the actor really does have HIV.”

“In this case, the actor and production company thought he was HIV-negative during filming,” the alert states.
