An individual's risk of acquiring or transmitting a sexually transmitted disease or HIV is affected both by individual risk factors and by one's location within a sexual network. Therefore, prevention efforts must consider intervening with both individuals and with network conformations. Helping gay and bisexual men make more informed choices about their partners and fragmenting networks to reduce the likelihood of risky encounters between high-risk core group members and those at lower risk are two strategies for reducing transmission in this population. Network-level interventions are particularly well suited for places such as commercial sex venues and Internet sites where gay and bisexual men meet new sexual partners.
个体感染或传播性传播疾病或艾滋病毒的风险既受个体风险因素影响，也受其在性网络中的位置影响。因此，预防工作必须考虑对个体和网络结构进行干预。帮助男同性恋者和双性恋男性在选择伴侣时做出更明智的选择，以及打破网络结构以减少高危核心群体成员与低风险者之间发生危险接触的可能性，是减少该人群中疾病传播的两种策略。网络层面的干预措施特别适用于商业性交易场所和男同性恋者及双性恋男性结识新性伴侣的互联网网站等场所。
