Objective To evaluate the reported incidence and prevention and control effect of tuberculosis (TB) in Sichuan province during the 13th five-year plan period, and provide reference for the key prevention and control points of TB in Sichuan during the 14th five-year plan period.
Methods The reported incidence data of TB in Sichuan from 2016 to 2020 were collected from the Surveillance System for Infectious Diseases for a descriptive statistical analysis.
Results From 2016 to 2020, both the number of reported cases and the reported incidence of TB in Sichuan decreased year by year, with an average annual decrease rate of 5.35%. The reported TB incidence in 2020 was 55.19/100 000. The proportion of TB cases with sputum etiological positive results continued to increase, reaching more than 50% in 2020. The number of reported TB cases fluctuated obviously around the Spring Festival period, especially in 2020 with a decrease of 20.76% in February compared with January and an increase of 30.87% in March compared with February.
