The announcement of a fourth porn star testing HIV-positive has resulted in the industry’s third shutdown of the year last Friday.

The identity of the adult entertainer has not been publicly disclosed by the officials with the Free Speech Coalition (FSC) — an industry trade group that oversees the testing of adult entertainers for sexually transmitted infections (STIs) — who called for a moratorium on filming. The HIV-positive result came from a testing center in Los Angeles, The Los Angeles Times reports.

The adult-film industry trade group is currently working to identify the partners of the performer who tested positive for HIV. Additional tests will be performed by the coalition, including determining a timeline as a means of accurately identifying the performer’s partners.

“We take the health of our performers very seriously and felt that it was better to err on the side of caution while we determine whether anyone else may have been exposed,” Diane Duke, the coalition’s chief executive, told The Times.

The second wave of HIV-positive porn performers has prompted the agency to do STI testing on the stars every 14 days, which is twice as often as before, The Associated Press reports. The agency’s protocols have been designed to provide a conservative approach to protect the health and well-being of the performers.

The first porn industry shutdown in August came as a result of actress Cameron Bay who tested HIV-positive. The 28-year-old porn star’s HIV diagnosis brought the industry to a halt six days later by the FSC. A week after the FSC lifted the moratorium, Bay’s boyfriend, porn star Rod Daily, publicly announced on Twitter that he was also HIV-positive: 

The FSC didn’t do another moratorium because Daily’s was not officially reported.

Following Daily’s announcement, an industry-affiliated doctor contacted the coalition with results of a third HIV-positive unidentified performer. The AP reports, the third incidence prompted the FSC to impose a second moratorium on September 6 which lasted two weeks. The agency does reveal the first three performers who recently tested HIV-positive did not contract the virus on a film set.

Michael Weinstein, president of the AIDS Healthcare Foundation, an advocacy group currently pushing for a statewide requirement of condoms being used on adult film sets, remains upset with the lack of government involvement despite the recent moratoriums. “Are we still going to be having this argument when there’s the 10th shutdown or 20th? Or the 50th infection?” he told the L.A. Times.

He hopes the third moratorium will push government officials to enforce Measure B, a voter-backed law that requires condom use in porn films in Los Angeles County. Under the measure, porn producers would have to pay for a permit to film and to submit to inspections by the L.A. County Public Health Department.

Vivid Entertainment and two porn stars oppose the measure, arguing that a condom mandate limits the freedom of expression of the producers and performers. While U.S. District Judge Dean Pregerson said the way the condoms are enforced under the measure are unconstitutional, it still upheld the basic mandate or requiring condoms. he condom mandate law was originally drafted by the AIDS Healthcare Foundation who believes it would be a more proactive decision in addition to the STI testing.  

The Food and Drug Administration (FDA) says condoms are not 100 percent safe, but they can reduce the risk of STIs, including AIDS, if used properly. More than 1.1 million people in the U.S. are living, with almost one in six unaware of their infection. Gay, bisexual, and other men who have sex with men are most affected by the virus.
