ABSTRACT

Objective:

To explore the tuberculosis (TB) clustering areas and changing tendency in China from 2013 to 2018, so as to provide evidence for improving the control and prevention programs on TB.

Methods:

Spatial distribution of TB in China from 2013 to 2018 was studied using data from TB information management system of Chinese disease prevention and control information system. The SaTScan 9.6 software was used to detect and analyze the TB clusters and relative risks. Likelihood ratio and P value under the scan windows were used as the main index to define the clusters.

Results:

The TB registration rate declined in China from 2013 to 2018. High-risk clusters were mainly located in western regions of Xinjiang, Tibet, Shaanxi, Sichuan, Chongqing, Yunnan, Guizhou, Guangxi provinces and central and eastern regions of Inner Mongolia, Hubei, Hunan, Jiangxi, Guangdong and Hainan provinces. The number of counties with TB clusters declined slowly, from 1 112 in 2013 to 806 in 2018. In comparison with areas other than the clusters, the RR of TB in the clusters remained at high levels in southern Xinjiang and western Tibet from 2013 to 2018 (RR>3.0).

Conclusions:

The number of the counties with TB clustering declined slowly from 2013 to 2018, and most of them were located in western and central China. Early detection and health education should be focused on TB patients to prevent the spread of TB. Management programs set for TB patients should be strengthened, especially in the western parts of the country where TB clusters and high relative risks existed.
