Abstract:

Objective: To analyze the epidemic characteristics of MTB/HIV double infection in Changsha, and to improve the prevention and control strategies. Methods: The data of MTB/HIV dual infection patients in Changsha from 2011 to 2020 were extracted from Tuberculosis Information Management System and TB/HIV Dual Infection Prevention and Management Annual Report, to establish a comprehensive database of MTB/HIV characteristics and distribution in Changsha. The detection of MTB/HIV dual infection, description of the annual change trend and the epidemic distribution characteristics in different time, gender, age and region were analyzed. Results: From 2011 to 2020, a total of 280 MTB/HIV double infection cases were found in Changsha, the patient detection rate fluctuated with the year (4.29% (12/280)-15.36% (43/280)). Among them, HIV infection were detected in 39 tuberculosis patients, with an annual detection rate of 0.10% (39/38990). The HIV positive rate showed an increasing trend of fluctuation in different years (0.03% (1/3759)-0.22% (9/4057))(Z=2.347, P=0.019). Among HIV/AIDS patients, MTB infection were detected in 241 cases, and the average annual detection rate was 0.68% (241/35381). The detection rate of tuberculosis showed a decreasing trend with fluctuation in different years (0.41% (19/4639)-2.13% (13/610))(Z=-6.126,P=0.001). The 280 MTB/HIV dual infected patients were mainly male (85.71% (240/280)); and the age was mainly at 25-44 years (46.78% (131/280)), followed by 45-64 years old (32.50% (91/280)). As to regional distribution, Liuyang City had the most cases (26.07% (73/280)), followed by Changsha County and Ningxiang City (both 16.43% (46/280)). Conclusion: The level of MTB/HIV double infection in Changsha was low, but the average annual detection rate of HIV infection among tuberculosis patients showed a fluctuating upward trend. The detection rate of MTB infection in HIV/AIDS screening showed a fluctuating downward trend. The prevention and control should be focused on male and 25-44 years age group, as well as people in areas with high prevalence of AIDS and tuberculosis.
