A year before the HIV virus was isolated and named, the San Francisco chapter of the Sisters of Perpetual Indulgence published a small pamphlet titled "Play Fair!" out of concern over widespread STIs among the city's gay male population. It specifically named illnesses (Kaposi's sarcoma and pneumocystis pneumonia) that would later be understood as symptoms of advanced HIV disease (or AIDS). The pamphlet advocated a range of safe-sex practices, including abstinence, condoms, personal hygiene, use of personal lubricants, and STI testing/treatment. It took a casual, sex-positive approach while also emphasizing personal and social responsibility. In May 1983—the same month HIV was isolated and named in France—the New York City-based HIV/AIDS activists Richard Berkowitz and Michael Callen published similar advice in their booklet, "". Neither publication used the term "safe sex" but both included recommendations that are now standard advice for reducing STI (including HIV) risks.
