Rates of new HIV acquisition remain unacceptably high in most populations in low-income, middle-income, and high-income settings despite advances in treatment and prevention strategies. Although biomedical advances in primary prevention of new infections exist, systematic scale-up of these interventions has not occurred at the pace required to end AIDS by 2030. Low population coverage, adherence to oral pre-exposure prophylaxis in settings with high rates of HIV acquisition, and the fact that a significant proportion of new HIV infections occurs in populations not identified as high risk and are hence not targeted for prevention approaches impedes current prevention strategies. Although long-acting injectables and monoclonal antibodies are promising approaches to help reduce incidence, high cost and the need for high coverage rates mean that a vaccine or vaccine-like intervention still remains the most likely scenario to produce a population-level impact on HIV incidence, especially in countries with generalised epidemics. Current global efforts are not sufficient to meet 2030 HIV epidemic goals; acknowledgment of this issue is required to ensure persistent advocacy for population-based control of the ongoing HIV pandemic.
尽管在治疗和预防策略方面取得了进展,但在低收入、中等收入和高收入国家的大多数人群中,新的 HIV 感染率仍然高得令人无法接受。尽管在新感染的初级预防方面存在生物医学方面的进展,但这些干预措施并没有以 2030 年终结艾滋病所需的速度系统地扩大规模。低人群覆盖率、在 HIV 感染率高的环境中坚持口服暴露前预防、以及相当一部分新的 HIV 感染发生在未被视为高危人群的人群中,这使得目前的预防策略受到阻碍。尽管长效注射剂和单克隆抗体是帮助降低发病率的有希望的方法,但高成本和高覆盖率的需求意味着疫苗或类似疫苗的干预措施仍然是在 HIV 发病率方面对人群产生影响的最有可能的方案,特别是在普遍流行的国家。目前的全球努力不足以实现 2030 年艾滋病毒流行目标;必须承认这一问题,以确保持续倡导以人群为基础控制正在发生的艾滋病毒流行。
