Objective To understand the incidence trend and epidemiological characteristics of pulmonary tuberculosis (TB) in Foshan, Guangdong province, and provide evidence for the development of local TB prevention and control strategies.
Methods We compared the incidence data of pulmonary TB reported in Guangdong and Foshan from 2010 to 2020 collected from "China Information System for Disease Control and Prevention", and the age, gender and occupation specific changes in the incidence of pulmonary TB were analyzed.
Results From 2010 to 2020, the reported incidence of pulmonary TB in Foshan had an average annual decline of about 9.28%, and an average annual decline rate of 7.03 per 100 000 (t=−12.68, P<0.0001), both decreased faster than those of Guangdong province. The gap in pulmonary TB incidence levels among the counties and districts have gradually become smaller. The male to female ratio of the pulmonary TB cases was 1∶0.40 (t=20.06, P<0.0001), and the cases decreased in younger age groups but increased in older age groups. The cases were mainly the jobless or unemployed, workers and farmers, accounting for about 65.38%. It is predicted that the pulmonary TB incidence rate in Foshan would decrease to <10/100 000 by 2035 based on the decrease level in the past 10 years.
Conclusion The incidence of TB declined rapidly in Foshan after taking a series of prevention and control measures. In the future, it is necessary to develop new TB prevention and control strategies, further increase investment, strengthen the TB prevention service system, improve people’s health and health insurance and promote the application of innovative technologies and smart tools according to the epidemiological characteristics of TB to improve TB prevention and control.
