Abstract:

Currently, the slow decline of tuberculosis incidence rate becomes a huge challenge to the goal of ending tuberculosis. In 2020, the estimated global latent tuberculosis infection (LTBI) population was nearly 2 billion. With the condition of no preventive intervention, 5% to 10% of them will develop into active tuberculosis in the lifetime, and the incidence rate is higher in high-risk population. The World Health Organization has called for the promotion of the prevention of LTBI worldwide, so as to achieve the goal of a rapid decline in the incidence rate of tuberculosis. This paper reviews the current situation of LTBI epidemic and preventive treatment, the incidence risk of high-risk population, screening methods, intervention and management suggestions, etc., in order to provide reference for formulating LTBI intervention and management strategies and measures in China.

Key words: Mycobacterium tuberculosis, Infectious disease incubation period, Diagnosis, Protective agents
