The porn industry may be facing a HIV epidemic as reports of a fourth infected actor has surfaced.

Tests have confirmed adult film stars Cameron Bay, Rod Daily and two unnamed actors are HIV positive, according to RadarOnline.com.

"I can confirm," AIDS Healthcare Foundation president Michael Weinstein told Radar about the fourth infected actor. "However, he has asked that all other information be kept strictly confidential at this time."

The AIDS organization has been fighting California lawmakers to make condoms a legal requirement on set.

The infections are a big deal in the porn industry.  Though the Free Speech Coaliton regulates testing of porn actors every 14 or 28 days and cannot perform without being cleared of sexually transmitted diseases, it was not enough to keep the infection from spreading. 

According to ABC News, "the Los Angeles County porn industry hasn't had a performer test positive for HIV since 2004, and that performer didn't contract the virus from the porn community."

There are no confirmed reports any of the infections occurred on set.

However, adult film actors are reportedly at a higher risk of contracting STDs.  Rod Daily took to Twitter to announce his HIV infection, and spoke about the dangers of the disease.  The actor said his first HIV test came back negative, while his second was positive and confirmed by the Free Speech Coalition.

"Just sayin be careful because that test ain't s**t without a condom strapped up with it," the actor tweeted.

Joanne Cachapero, membership director of the Free Speech Coalition, told Reuters the group is investigationg to find the source of the infection.

"While we don't have evidence to suggest an on-set transmission as opposed to a transmission from non-industry (off-camera) related activity, we are taking every measure to determine the source and to protect the performer pool," Cachapero said in a statement.
