As discussed by Rotheram-Borus, Gillis, Reid, Fernandez, and Gwadz (1997), YMSM who engage in HIV-related risk acts are more likely than their hetero sexual or bisexual counterparts to get tested, and those highest at risk continue to get retested for HIV over time. Although getting tested does not constitute HIV preven tion per se, knowledge of one’s serostatus is and will continue to be a vital part of controlling the spread of the AIDS epidemic.
