An adult industry performer who tested positive this week for HIV shot her most recent sex scene with Xander Corvus — the man who starred as Anthony Weiner in Sydney Leathers' just released porn debut "Weiner and Me."

Cameron Bay, who has appeared in adult films since 2010 under various names, confirmed to AVN late last night that she was the performer responsible for the moratorium on porn production announced yesterday.

Cutting Edge Testing lab told Bay on Wednesday that a blood sample drawn on Tuesday came back positive for HIV.

She told AVN that she was "obviously extremely distraught and in disbelief," and that an additional test will be conducted to confirm the result.

According to Bay, she received her last clean bill of health on July 27th.

Just a few days later she filmed an unprotected sex scene for the ongoing series Public Disgrace [NSFW].

Her male partner was a freelance actor named Xander Corvus — most recently known for having similarly unprotected sex with Sydney Leathers for [NSFW].

Making matters worse for all involved is the fact that Bay had not performed in any additional films since appearing in the notoriously brutal Public Disgrace series because of an injury she sustained on set.

On her Twitter feed, Bay said that one of the extras hired by "did not listen to the rules and hit me to (sic) hard."

Though Bay told AVN her last on-screen sex took place on July 31st, she posted the first tweet about her injury on August 3rd.

That same day she also posted a "behind the scenes" photo of herself entitled "Before my PUBLIC DISGRACE SCENE."

In a statement to Gawker, Leathers said both she and Xander got tested prior to shooting their scene, and both were deemed "healthy."

An additional test Leathers says she underwent in NYC after the shoot also came back negative.

It's worth noting that negative test results within the first 3 months of exposure could be false, according to the CDC.

It takes the body an average of 25 days to produce antibodies against HIV, which means rapid tests may not be able to detect HIV in a person if conducted within the "window period" before a definitive result can be returned.

The CDC recommends that individuals who have been exposed to HIV and have been found negative before three months have elapsed get retested after three months and avoid having sex in the interim.

Meanwhile, Diane Duke, who heads the porn industry trade organization FSC (Free Speech Coalition), said her group was working with Adult Production Health and Safety Services to ensure that anyone potentially exposed to HIV is tested.

"The moratorium will be lifted once the risk of transmission has been eliminated," she told the Associated Press.

Voters in Los Angeles County last year approved Measure B, which requires adult entertainers to wear protection while shooting adult films.

Vivid Entertainment and several high-profile porn stars sued the county to prevent implementation of the restriction, calling it "unconstitutional."

The county refused to defend the measure, forcing the AIDS Healthcare Foundation to take its place.

UPDATE: Adult Talent Managers LA, which represents Cameron Bay, has released a statement to Gawker saying: "We can not comment other than to say that proper protocols regarding notifications are in place."
