The phase specific model for the prevention and control of sexually transmitted infections (STI) offers new insights into the strategic planning of programmes. The model illustrates the importance of modifying the focus of prevention and control activities to different subpopulations as the epidemic evolves over time. However, the practical application of phase specific approaches will depend on an understanding of the variability and determinants in the trajectory by which STI epidemics progress through epidemic phases. This paper draws on empirical observations from diverse populations to explore the influence of sexual behaviour patterns in populations, the biological characteristics of STI pathogens, and the population-pathogen interactions in relation to epidemic trajectories. In addition, various approaches to the determination of epidemic phase are presented.
性传播感染（STI）预防与控制的阶段特异性模型为项目的战略规划提供了新的见解。该模型表明，随着疫情随时间演变，将预防与控制活动的重点针对不同亚人群进行调整具有重要意义。然而，阶段特异性方法的实际应用将取决于对性传播感染疫情在不同流行阶段发展轨迹中的变异性和决定因素的理解。本文借鉴来自不同人群的实证观察结果，探讨人群性行为模式、性传播感染病原体的生物学特性以及与流行轨迹相关的人群 - 病原体相互作用的影响。此外，还介绍了确定流行阶段的各种方法。
