Objective@#To investigate the epidemiological characteristics of pulmonary tuberculosis in Ningbo City from 2011 to 2020, so as to provide the evidence for developing the control measures of pulmonary tuberculosis.@*Methods@#The data pertaining to pulmonary tuberculosis cases in Ningbo City from 2011 to 2020 were collected from the Tuberculosis Management Information System of the Chinese Disease Control and Prevention Information System. The temporal distribution, population distribution, regional distribution and case report by hospitals were descriptively analyzed.@*Results@#Totally 38 305 pulmonary tuberculosis cases were reported in Ningbo City from 2011 to 2020, with an incidence rate of 48.71/105. The incidence of pulmonary tuberculosis appeared a tendency towards a decline ( P<0.05 ), with an annual reduction rate of 5.29%. There were 15 784 smear-positive cases ( 41.21% ), and the proportion of smear-positive cases appeared a tendency towards a reduction from 2011 to 2015 ( P<0.05 ), and a rise from 2016 to 2020 ( P<0.05 ). The number of reported pulmonary tuberculosis cases peaked from March to May (10 973 cases, 28.65%), and a higher incidence rate of pulmonary tuberculosis was found in men than in women ( 64.55/105 vs. 32.20/105, P<0.05 ). The highest incidence of pulmonary tuberculosis was found in cases at ages of 15 to 25 years ( 72.93/105 ), followed by in cases at ages of 65 years and greater ( 69.97/105 ), and farmers were the predominant occupation among the pulmonary tuberculosis patients ( 12 279 cases, 32.06% ). During the period from 2011 to 2020, pulmonary tuberculosis cases were reported across the 10 districts or counties of Ningbo City, and the top three high incidence of pulmonary tuberculosis were seen in Yinzhou District ( 59.91/105 ), Fenghua District ( 56.19/105 ) and Beilun District ( 56.01/105 ). The proportion of pulmonary tuberculosis cases reported by designated pulmonary tuberculosis hospitals increased from 72.16% in 2011 to 99.74% in 2020 in Ningbo City.@*Conclusions@#The incidence of pulmonary tuberculosis appeared a tendency towards a decline in Ningbo City from 2011 to 2020, and the annual decline rate meets the requirements of the WHO strategic goal of ending pulmonary tuberculosis; however, the control measures for pulmonary tuberculosis require to be intensified among men, youths, and farmers.
