RESUMO
Objective To explore the epidemic characteristics and spatial clustering of pulmonary tuberculosis in Wuhan from 2011 to 2019, and to provide a scientific basis for formulating intervention strategies and measures. Methods Descriptive statistical analysis was conducted on the epidemic characteristics of tuberculosis data in Wuhan registered in the national tuberculosis information management system in the last 9 years, and spatial autocorrelation analysis was performed on the incidence of tuberculosis in 155 communities or in the city using Arcgis10.5 software. Results From 2011 to 2019, there were 56,432 cases of tuberculosis reported in Wuhan, and the annual average reported incidence rate of tuberculosis was 59.24/100 000. The overall incidence rate showed a fluctuating downward trend, with an average annual decline rate of 1.99%. The ratio of the number of cases between men and women was 2.35:1, and the incidence rate in males was higher than that in females (χ2=285.36，P0,P<0.001), and the high-high aggregation areas of tuberculosis were mainly distributed in Erqi community, Baibuting community, Liujiaoting community, Yijiadun community, Heping Street, Changqian Street, Tonghu farm, Yuxian Town, Zhifang Town, Wulijie Town, Fenghuang Street, Liji Street, and Daoguanhe Street. Conclusion The overall epidemic situation of pulmonary tuberculosis in Wuhan showed a slow downward trend. The main population and the clustering time of cases were relatively fixed, and the overall epidemic showed a certain spatial clustering. Active screening should be carried out for high-risk populations and high-aggregation areas, and effective prevention and control strategies should be developed based on time and location classification.
RESUMO
Objective@#To analyze the epidemiological characteristics, trend and related factors of tuberculosis patients that delayed for care, in Wuhan from 2008 to 2017.@*Methods@#Data regarding tuberculosis (TB) patients was collected from the tuberculosis management information system (TMIS), a part of the China information system for disease control and prevention from 2008 to 2017. A total of 64 208 tuberculosis patients, aged 0 to 95 years were included for the analysis. Unconditional logistic regression method was used to estimate those factors that associated with this study.@*Results@#Days of delay among TB patients appeared as M=10 (P25-P75: 3-28) day, in Wuhan, 2008-2017. The prevalence of the delay was 52.5% (33 703/64 208), presenting a downward trend from 2008 to 2017 (trend χ2=10.64, P<0.001), but the proportions of women and ≥65 year-olds were gradually increasing. Results from the multivariate logistic regression analysis showed that factors as: patients living far away from the city vs. near the city (OR=1.29, 95%CI: 1.25-1.35), and age above 45 years vs. younger than 25 years (the age 45-64 years group vs. aged less than 25 years group, OR=1.22, 95%CI: 1.15-1.29; the age 65 or above group vs. aged less than 25 years group, the OR=1.30, 95%CI: 1.22-1.39) were under higher risk on the delay of seeking care. Occupation, way of case-finding and classification of tuberculosis patients also appeared as influencing factors on this issue.@*Conclusions@#Prevalence on the delay of care was 52.5% among tuberculosis patients in Wuhan, 2008-2017, but with an annual decrease. Attention should be paid to female, wrinkly or elderly tuberculosis patients regarding the delay of care on TB, in Wuhan.
RESUMO
Tuberculosis is recognized as a chronic respiratory infectious disease and still one of the important public health issues in the world.Douglas reported an unique seasonal pattern (summer peak) of tuberculosis,when compared with most other respiratory diseases in 1996.Since then,there had been many other researchers notified various patterns of seasonality on TB.This paper reviewed all the studies published in the last five years and analyzed the current findings on seasonal variability and influencing factors,in order to explore the risk factors to provide evidence for prevention and control strategies on tuberculosis.
