AIM Healthcare clinic administrator Brooke Hunter said they are quarantining and testing all exposed partners to the individual, according to the LA Times.
Hunter would not release any further details about the individual, but said they are doing everything they can to notify the individuals involved.
FSC's Diane Duke told XBIZ that AIM responded in a professional manner and is waiting to find out more information about the case.
"AIM responded quickly to the matter and is taking care of the needs of all the people involved."

Meanwhile, the AIDS Healthcare Foundation, which has been leading efforts to change California worker-safety health code, held a press conference this afternoon to address the HIV case.
“That a performer tested positive for HIV today — and that more may be infected — was totally preventable,” said Michael Weinstein, president of AIDS Healthcare Foundation.
“It is also living proof that testing is not adequate protection against HIV/AIDS and other sexually-transmitted diseases among porn performers."
XBIZ will update the story with more information as it becomes available.
