Large declines in HIV incidence have been reported since 2001, and scientific advances in HIV prevention provide strong hope to reduce incidence further. Now is the time to replace the quest for so-called silver bullets with a public health approach to combination prevention that understands that risk is not evenly distributed and that effective interventions can vary by risk profile. Different countries have different microepidemics, with very different levels of transmission and risk groups, changing over time. Therefore, focus should be on high-transmission geographies, people at highest risk for HIV, and the package of interventions that are most likely to have the largest effect in each different microepidemic. Building on the backbone of behaviour change, condom use, and medical male circumcision, as well as expanded use of antiretroviral drugs for infected people and pre-exposure prophylaxis for uninfected people at high risk of infection, it is now possible to consider the prospect of what would be one of the most remarkable achievements in the history of public health: reduction of HIV transmission from a pandemic to low-level endemicity.
自 2001 年以来,报告显示艾滋病毒发病率大幅下降,艾滋病毒预防方面的科学进步为进一步降低发病率带来了巨大希望。现在是时候用综合预防的公共卫生方法取代对所谓的灵丹妙药的追求了,这种方法认识到风险并非均匀分布,有效的干预措施可能因风险状况而异。不同的国家有不同的微观流行情况,传播和风险群体的水平差异很大,并且随着时间的推移而变化。因此,应将重点放在高传播地区、艾滋病毒感染风险最高的人群以及在每种不同微观流行情况下最有可能产生最大效果的干预措施组合上。在行为改变、 condom 使用和医学男性包皮环切术的基础上,扩大对感染人群的抗逆转录病毒药物的使用以及对高感染风险的未感染人群进行暴露前预防,现在我们可以考虑一个可能成为公共卫生史上最显著成就之一的前景:将 HIV 传播从大流行降低到低水平地方性流行。
