"When Vivid was first made aware that a performer had tested positive for HIV we immediately suspended production," Steven Hirsch, Vivid's co-founder, told the Los Angeles Times.
"We did this as a precaution and will continue to monitor the situation. AIM Healthcare acted appropriately to quarantine all adult talent who may have been exposed. We will wait for all of the facts to emerge before we resume production.
"Even though Wicked is condoms-mandatory, we have postponed our upcoming productions to give AIM a chance to create a comprehensive quarantine list," Wicked officials said. "Thanks to the continued efforts of AIM the entire industry was all made aware of this possible threat on the same day."
AIM spokeswoman Jennifer Miller, aka Brooke Hunter, said the case revealed today involves an unidentified adult-film performer who tested positive at AIM's Sherman Oaks branch.
Miller declined to reveal the gender of the performer or the companies he or she worked for.
"We do have a confirmed adult-industry performer who tested positive for HIV. We are quarantining and testing all exposed partners to the individual who tested positive for HIV," Miller said.
"We’re doing what we can to notify the individuals involved," Miller said.
