The porn industry may not be as clean as it claims: “There have been 16 unpublicized cases of HIV among porn actors since a 2004 outbreak made headlines,” according to Reuters. The news comes on the heels of the revelation by the Los Angeles Times that an unidentified actress tested positive for the virus last week. That brings the total of performers to test positive up to 22 since 2004, when a male star infected three actresses and the industry started requiring regular testing by its actors. HIV is more common in the industry now than syphilis, of which there have been 15 cases since 2004. There have been 1,357 cases of gonorrhea.
