Abstract:

Objective Analysis of the epidemic characteristics of rifampicin-resistant pulmonary tuberculosis (“RR-TB” for short) in Ganzhou, Jiangxi from 2019 to 2020. Methods The data of medical record information and drug resistance of registered patients with tuberculosis in Ganzhou City from January 1, 2019 to December 31, 2020 were derived from the Tuberculosis Management Information System, a subsystem of China Disease Control and Prevention Information System. The status of cases tested for resistance and epidemiological characteristics of RR-TB cases were analyzed. Results Among the 10508 pulmonary tuberculosis patients who registered in Ganzhou from 2019 to 2020, there were 5897 bacteriologically confirmed cases. The proportion of bacteriologically confirmed tuberculosis cases tested for rifampicin resistance was 93.18% (5495/5897), and the prevalence of rifampicin resistance was 5.55% (305/5495). The proportion of RR-TB cases from new bacteriologically confirmed retreatment bacteriologically confirmed tuberculosis cases and from retreatment bacteriologically confirmed tuberculosis cases were 49.51% (151/305) and 50.49% (154/305), respectively. The prevalence of rifampicin resistance among who aged 20-59 years (6.25% (199/3186)) was significantly higher than that among who aged 0-19 years (3.74% (8/214)) and who aged greater than 60 years (4.68% (98/2095));the prevalence of rifampicin resistance among Nankang District (9.06% (30/331)) of urban and neighboring suburbs was significantly higher than that among Shicheng County (1.35% (3/222)) of outside suburban district. The differences were statistically significant (the Chi Squares were 7.324,766.858, and the P values were 0.026,0.001). Conclusion Rifampicin resistant tuberculosis has became an important challenge in the prevention and control of tuberculosis in economic undeveloped areas. Standard treatment and infection control should be further strengthened to reduce the occurrence of drug resistance,young and middle-aged population and cases in urban and neighboring suburbs should be the key populations.
