实事求是抓住核心脚踏实地精准防控

Tuberculosis control strategy based on the discovery of infectious sources

随着WHO提出2035年消灭结核病的伟大目标,对结核潜伏感染者进行预防性干预作为重要的创新策略受到了国内外的重视。中国是全球结核病第二高负担国家,结核病防控形势十分严峻。在这种情形下更需要对我国结核病疫情保持清醒的认识,抓住结核病控制的核心和重点。作者从结核潜伏感染的定义、潜伏感染人群发病的时间,以及国外结核病控制的成功经验等方面,进一步说明在结核病高负担国家,近期传播是导致结核病高疫情的主要原因,发现传染源仍然是目前结核病控制的核心;同时,提出重视留取痰液质量和建立区域性实验室是提高我国病原学检测能力、发现传染源、控制结核病传播的重要手段。

With WHO's grand goal of eliminating tuberculosis by 2035,preventive interventions for latent infections of TB have received significant attention as innovation strategies.China is the second-highest TB burden country in the world.It is even more necessary to understand the tuberculosis epidemic in China and to grasp the critical points of tuberculosis control.Wc reviewed the definition of latent infection,the incubation period of latent infection,and the successful experience of tuberculosis control in abroad.We emphasize that the new transmission is the leading cause for high TB burden countries,and discovery the source of infection is still the key for the TB control program.At the same time,it is an essential means to improve the quality of sputum and establish regional laboratories to enhance the ability of detection of TB in China,and to control the transmission of TB.
