Abstract: Objective Through epidemiological study of bacteriological positive pulmonary tuberculosis cases at Chinese frontier ports,we aim to master the spread conditions and determine important population to take derect measures of prevention and control for bacteriological positive pulmonary tuberculosis prevalence.Methods We analyze bacteriological positive pulmonary tuberculosis’ data from all Inspection and Quarantine authorities in China and use epidemiological study to describe the recorded data.Results The highest bacteriological positive pulmonary tuberculosis rate ports are Heilongjiang port(76.27/10000)、Guizhou port(26.32/10000)、Zhuhai port(15.29/10000)、Shanxi port(14.83/10000)、Anhui port(14.52/10000).The majority of bacteriological positive pulmonary tuberculosis cases outside border are from East Asia.Most of the bacteriological positive pulmonary tuberculosis cases are middle-young aged men.Entry-exit persons within the border that bacteriological positive pulmonary tuberculosis detection rate is higher are drivers,people who marry with foreigners,businessmen,sailers and entry-exit persons outside border are sailers,service workers,businessmen.People within the border bacteriological positive pulmonary tuberculosis detection rate(6.00/10000) is much higher than that of people outside borders(2.00/10000).Conclusions We need to strengthen the surveillance of the high risk population and educate the population about the potential spread and information related to bacteriological positive pulmonary tuberculosis,in order to effectively prevent the spreading of pulmonary tuberculosis through these frontier ports.
