   • 1991 December 8, Jacob Smith Yang, “'Invasive Procedures' Dropped?”, in Gay Community News, volume 19, number 21, page 1:

     CDC guidelines issued in July called for voluntary HIV testing of all health care workers, but also recommended that those who are found HIV positive go before a local board that could advise them not to perform a list of "exposure-prone" procedures. AIDS activists and health care workers decried the guidelines, arguing that they served as a disincentive for health workers to seek HIV testing. They also charged that the recommendations legitimized public fear about HIV transmission during surgical or dental procedures.
