LOS ANGELES -- A fourth pornography actor has tested positive for the AIDS virus in an outbreak that has prompted Southern California's adult-movie industry to halt production, according to an organization that tests the performers for HIV.
The actor, a transsexual named "Jennifer," was diagnosed Tuesday in a case that appeared to be unrelated to the three earlier cases, according to a statement from the Adult Industry Medical Health Care Foundation.
Two of Jennifer's on-screen sex partners have tested negative at least once since their last encounter with the actor Feb. 27. Jennifer has not worked in the industry since then, so the foundation said it considered the case isolated.
In April, an actor with the screen name Darren James and a woman he performed with tested positive. Their cases prompted a voluntary quarantine of more than 50 adult-movie performers and halted productions by about 30 film companies, most of which operate in the San Fernando Valley.
James apparently contracted HIV while filming unprotected sex scenes in Brazil, health officials have said.
The third case was announced last week.
AIM is run by former porn star Sharon Mitchell, who holds a doctorate in human sexuality. Since the organization opened in 1998, Mitchell has provided testing for sexually transmitted diseases along with drug and psychological counseling for porn performers.
The last HIV scare in the porn industry was in 1999 and involved a single case.
