Despite porn industry assurances that an adult film actress' recent positive HIV test is the first since a 2004 outbreak shut down production for a month, Los Angeles County health officials said Thursday that at least 16 additional unpublicized cases of HIV have been confirmed in adult film performers.

The newly released data bring the number of HIV cases in porn performers in the last five years to 22, including the case disclosed this week.

The actress had two recent sexual partners, according to AIM. One is a porn actor, now under work quarantine, who performed with the woman June 5. The other is her boyfriend. Those men have had sexual intercourse with an additional six people, who have all been notified and offered testing, Hamblin said. So far, no one known to have had contact with the woman or her partners has tested positive for HIV.
