In ending a two-week moratorium on filming, the group Free Speech Coalition said actors would now be required to be tested for the virus twice as often, the Los Angeles Times reported Monday.
All adult film actors must be tested every 14 days for the human immunodeficiency virus, which causes AIDS, the organization said. Previously, testing was required every 28 days.
Testing will be required again on or after Thursday for performers to return to work.
Free Speech Coalition called for a moratorium last month after it said a 28-year-old porn actress known as Cameron Bay tested positive for HIV. After the moratorium was lifted, the actress's real-life boyfriend and fellow performer, Rod Daily, announced he had tested positive for HIV.
The moratorium was reinstated after a third unnamed performer tested positive.
