Since 1989, the USA has been pursuing the goal of tuberculosis elimination. After substantial progress during the past two decades, the rate of tuberculosis cases in the USA each year has now levelled off and remains well above the elimination threshold. Both epidemiological data and modelling underline the necessity of addressing latent tuberculosis infection if further progress is to be made in eliminating the disease. In this Personal View we explore next steps towards elimination. Given the estimated prevalence of latent tuberculosis infection, compared with the limited testing and treatment that currently occur, a major new effort is required. This effort should consist of a surveillance system or registry to monitor progress, scale-up of targeted testing for latent tuberculosis infection in at-risk populations, scale-up of short-course treatment regimens, engagement of affected communities and medical providers who serve those communities, and increased public health staffing for implementation and oversight. Such an effort would benefit greatly from the development of new tools, such as tests that better indicate reactivation risk, and even shorter latent tuberculosis infection treatment regimens than currently exist.
自1989年以来,美国一直致力于实现消除结核病的目标。在过去二十年取得显著进展之后,美国每年的结核病病例率现已趋于平稳,但仍远高于消除阈值。流行病学数据和模型均强调,如果要在消除该疾病方面取得进一步进展,就必须应对潜伏性结核感染。在这篇个人观点文章中,我们探讨了迈向消除结核病的后续步骤。鉴于潜伏性结核感染的估计患病率,与目前有限的检测和治疗情况相比,需要做出重大的新努力。这项努力应包括一个监测系统或登记处,以监测进展情况;扩大对高危人群潜伏性结核感染的针对性检测;扩大短程治疗方案;让受影响社区以及为这些社区服务的医疗服务提供者参与进来;增加公共卫生工作人员以进行实施和监督。开发新工具将极大地推动这项工作,例如能更好地指示复发风险的检测方法,以及比现有方案更短的潜伏性结核感染治疗方案。
