Abstract:
Objective To investigate the epidemiological trends,temporal and spatial distribution characteristics of pulmonary tuberculosis in Lanping County.Methods Based on tuberculosis management data and basic information systems from the"China Disease Prevention and Control Information System,"pulmonary tuberculosis data from Lanping County for 2018-2023 were obtained.Descriptive epidemiology,concentration method,circular distribution method,and spatial autocorrelation analysis were used to conduct epidemiological and spatial analyses of the pulmonary tuberculosis data.Results A total of 2836 TB cases were reported in Lanping County from 2018 to 2023,with an average annual incidence rate of 233.26 per 100000,showing a declining trend.The male-to-female ratio was 1.95∶1,with the highest incidence among individuals aged 60 and above(932 cases,32.86%).Cases were predominantly among farmers(91.01%)and the Lisu ethnic group(52.68%).TB incidence showed weak seasonality with a bimodal distribution,with primary peak occurring from October to March and secondary peak from June to August.Tu'e Township(324.74 per 100,000),Shideng Township(307.42 per 100000),and Jinding Town(260.98 per 100,000)had the highest incidence rates,accounting for 1,284 cases or 45.28%of the county's total cases.In 2020,the incidence of pulmonary tuberculosis in Lanping County showed a spatial clustering distribution(global Morans's I value<0,P value<0.05),with Shideng Township consistently showing high-low aggregation characteristics.Conclusion Between 2018-2023,while the tuberculosis incidence rate in Lanping County has declined,it still falls short of Yunnan Province's tuberculosis prevention and control targets,and the prevention and control work continues to face significant challenges.Strengthening screening of high-risk populations and providing medical support to remote areas will be key measures for future prevention and treatment.
