Porn Actress Who Tested Positive for HIV Working With Health Officials
A porn film actress who tested positive for HIV is "distraught" and working with health professionals to notify her past sexual partners, her agent says.
The 28-year-old performer goes by the screen name Cameron Bay, the Los Angeles Timesreported. Porn film production was halted after Bay tested positive for HIV. The moratorium will remain in effect until Bay's sexual partners have been tested and cleared, according to Free Speech Coalition, a trade organization for the adult film industry.
Bay went in Monday for her regular screening for sexually transmitted diseases and the results came back inconclusive, Mark Schechter, owner of Adult Talent Managers LA, told the Times.
A second test with a new blood sample was conducted Tuesday and preliminary results that came back Wednesday were potentially positive for HIV. Bay's last test prior to Monday took place July 27 and was negative. She has done film shoots since then, Schechter said.
"As difficult as this news is for me today, I am hopeful that no other performers have been affected. I plan on doing everything possible to assist the medical professionals and my fellow performers. Following that, my long-term plan is to take care of myself and my health," Bay said in a statement, the Timesreported.
Thousands of Men Warned About Faulty PSA Tests
Thousands of men in central Pennsylvania have been told that their blood tests for prostate cancer may have been inaccurate.
Pinnacle Health of Harrisburg sent letters to 7,500 men to alert them that a faulty chemical in their prostate-specific antigen (PSA) tests led to results showing higher levels of PSA than were actually present, ABC Newsreported.
Significantly elevated PSA levels may be a sign of prostate cancer and often lead to prostate biopsies. The faulty tests were used at Pinnacle from May 2012 to June 26, 2013.
It's likely that the Pinnacle Health patients are just the tip of the iceberg, because all lots of the "IMMULITE" PSA tests were recalled June 27 by Siemens Healthcare Diagnostics. The company shipped the faulty tests to labs from February 2012 through May 2013, ABC Newsreported.
Porn Industry Halted After Actor's Positive HIV Test
The U.S. porn industry has temporarily halted production of adult films after an actor tested positive for HIV, the virus that causes AIDS.
The performer wasn't named and officials didn't reveal when the positive test was recorded, CBS News/Associated Pressreported.
The actor's sex partners are undergoing tests by doctors with Adult Production Health and Safety Services, which works with the porn industry.
"The moratorium will be lifted once the risk of transmission has been eliminated," Diane Duke, executive director of the industry trade group the Free Speech Coalition, told the APin an email. The actor is not believed to have been infected on a film set, she added.
Last year, the porn industry briefly ceased filming after nearly a dozen performers were infected with syphilis. An HIV scare in 2011 also halted production, but filming resumed when a re-test showed the actor did not have HIV, CBS News/APreported.
