Info released today by county public health officials indicates there have been 22 positive HIV tests of porn performers since a scare shut down the adult video biz for a month in 2004. The total includes 16 previously unpublicized positives. Stories at the LAT and XBiz:

The previously unpublicized cases will probably shock adult industry workers, who repeatedly have described the new case as the first since 2004. It was not immediately clear whether any of the previously unpublicized HIV infections involved workplace transmission of the virus.

Officials from the San Fernando Valley-based Adult Industry Medical Healthcare Foundation released more details this afternoon about the most recent case. The actress tested for HIV on June 4 and the first positive result was returned Saturday, according to a statement from AIM founder Sharon Mitchell on her clinic’s website. The woman had last tested negative for HIV on April 29, Mitchell said.

Three others with connections to the woman have so far tested negative for HIV, according to the statement, including two men described as "industry partners."
