Each sexually transmitted disease (STD) epidemic evolves through predictable phases, shaped by a dynamic interplay among the pathogen, the behaviors of the subpopulations in which it emerges, and the prevention efforts that are developed to limit its impact. As STD epidemics move through these phases, the sexual and social networks that fuel them become located in subpopulations characterized by progressively higher rates of sex partner change and less contact with the health care system. As a result, phase-appropriate prevention strategies and research issues are essential to reducing STDs and their consequences.
每一种性传播疾病（STD）的流行都要经历一些可预测的阶段，这些阶段受到病原体、病原体出现的亚群体行为以及为限制其影响而开展的预防措施之间动态相互作用的影响。随着性传播疾病流行经历这些阶段，助长其传播的性和社会网络会出现在一些亚群体中，这些亚群体的特点是性伴侣更换率越来越高，与医疗保健系统的接触越来越少。因此，针对不同阶段的预防策略和研究问题对于减少性传播疾病及其后果至关重要。
