Abstract：Scan statistic is an effective method used in spatial epidemiology to evaluate or predict disease aggregation. More and more researchers use this method to study the aggregation of tuberculosis and its influencing factors and reveal the distribution and transmission regularity of tuberculosis from space perspective. Scan statistic has an extensive application prospect in the prediction of tuberculosis outbreak, and combining scan statisticwith the genotyping results ofMycobacterium tuberculosis can also detect the regional spread, recent transmission and transmission chain. At present, it is still an important subject worthy of further study in China. This paper describes the basic concept, method and principle of scan statistic and the current application status in tuberculosis.
