Abstract:

Objective: To know the impact of active case-finding (ACF) on tuberculosis epidemic in Southern Xinjiang (Aksu Prefecture, Hotan Prefecture, Kashgar Prefecture and Kizilsu Kirghiz Autonomous Prefecture). Methods: By using the reported tuberculosis cases in the National Infectious Disease Reporting and Management System between 2016 and 2020, we analyzed the tuberculosis reported incidences of different age groups, sex, and proportion of case occupations, compared data of ACF period (2018-2019) and pre-ACF period (2016-2017). In addition, 77 tuberculosis prevention health care worker were surveyed to get their attitudes and suggestions about ACF and the impact of COVID-19 response on tuberculosis control by self-designed questionnaire. A total of 77 questionnaires were sent out and 77 were retrieved (100% valid). Results: The average annual incidence in Southern Xinjiang increased from 389.47/100000 (73898/18974100) in pre-ACF period to 489.64/100000 (96341/19675800) during the ACF period, the difference was statistically significant (χ2=2210.320,P<0.05). In terms of gender and age distribution, the incidence rate of male was 531.17/100000 (52304/9847000) during ACF period, which was 36.07% higher than that of the pre-ACF period (390.36/100000,37503/9607400). The incidence of female was 448.04/100000 (44037/9828800) during ACF period, which was 15.31% higher than that of the pre-ACF period (388.56/100000, 36395/9366700). The incidence rates of 15-24, 25-34, and 35-44 age groups increased by 66.30%, 50.37%, and 49.18%, respectively during ACF period. In terms of occupational distribution, the proportion of farmers, houseworkers/unemployed, and students changed from 86.14% (63646/73898), 4.83% (3571/73898), 1.17% (866/73898) to 87.40% (84201/96341), 5.40% (5202/96341), 1.68% (1623/96341) respectively. 89.61% (69/77) of respondents thought ACF can help reduce tuberculosis epidemic quickly,93.51% (72/77) of respondents thought COVID-19 responses have impacts on tuberculosis epidemic. Conclusion: ACF has detected more tuberculosis patients in southern Xinjiang, reduced the transmission of tuberculosis, and could contribute to the rapid decline of the local tuberculosis epidemic.
