Prevalence and Risk Factors of Subclinical Tuberculosis in a Low-Incidence Setting in China.

Subclinical tuberculosis (TB) represents a substantial proportion of individuals with TB disease, although limited evidence is available to understand the epidemiological characteristics of these cases. We aimed to explore the prevalence of subclinical patients with TB and identify the underlying association between the subclinical TB cases in the study setting and the Beijing genotype. A retrospective study was conducted among patients with incident TB at the Fifth People's Hospital of Suzhou between January and December 2018.
