Objective: To analyze the relationship between the incidences of pulmonary tuberculosis and climatological changes from the year of 1997 to 2015 in China. Methods: The data of pulmonary tuberculosis in 1997-2015 were collected and compared with the change curve of meteorological factors. The influence of meteorological factors on the incidence of pulmonary tuberculosis was analyzed. Results: The incidences of pulmonary tuberculosis in the period from 1997 to 2015 showed that the incidences of tuberculosis have risen sharply to 96 per 100,000 population in 2002-2005. Meteorological data from 1997 to 2015 showed that the annual average temperature gradually increases, reaching a peak of 11.22℃ between 2005 and 2006. In 2002-2006, the extreme maximum temperature was lower, while the extreme minimum temperature was higher, but the corresponding average temperature was at high value. Between 2003 and 2006, rainfall increased year by year, and relative humidity remained high during this period. Conclusion: The incidence of pulmonary tuberculosis is consistent with the mean temperature change. Short-term extreme high temperature or low temperature weather may have little effect on the incidences of pulmonary tuberculosis. Large rainfall, higher relative humidity may increase the survival time of Mycobacterium tuberculosis, may be associated with an increase in the incidence of pulmonary tuberculosis.
