ABSTRACT
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.
ABSTRACT
Objective To describe the epidemiological characteristics and changing trend of HCV-related children in Henan province. Methods Data was analyzed based on the case-reporting records on hepatitis C from 2008 to 2013. Results The number of reported cases and incidence of HCV-related children had increased annually from 2008 to 2012. The reported incidence on HCV-related children increased from 2.37 per 100 000 in 2008,to 3.23 per 100 000 in 2012,but it decreased to 1.77 per 100 000 in 2013. Reported cases on females increased annually. The 0-1 age group had the largest proportion but it decreased annually. Large cities as Zhengzhou,had high incidence,and the mobile population within the province also showed an annual increase,from 49.02%in 2008,to 59.77%in 2013. Time between onset and diagnosis(days)of the disease increased and the M and IQR from 2008 to 2013 appeared as 0(0-2),0(0-2),1(0-2),1(0-3),1(0-5) and 1(0-3). Conclusion The incidence of HCV-related children in Henan province showed an annual increase,along with the increasing trend of mobile population in the province as well as the longer time span between onset and diagnosis of the disease. It is suggested that strengthening the program on monitor,as well as on effective prevention and control measures be in place accordingly. Targets should also be focused on pregnant women,migrants,other key groups,so as to better perform on early detection and treatment.

ABSTRACT
Objective To analyze the epidemiological characteristics and changing trend as well as the related affecting factors of hepatitis C in China.Methods Data analysis was performed based on the case-reporting data of hepatitis C from 1997 to 2011,using SPSS 19.0.Results The number of reported cases and incidence of hepatitis C had been increasing annually since 1997,especially in 2004.The hepatitis C reported incidence increased from 3.03 per 100 000 in 2004,to 12.97 per 100 000 in 2011.The 15 to 49 age group accounted for more than 50％ of all the reported cases,seen in every year.The number and proportion of hepatitis C reported cases among those over 50 year-olds had an annually increase.From 2005 to 2011,the number of cases in both urban areas and rural areas increased annually,while the urban-rural ratio decreased from 1.47 in 2005 to 0.99 in 2011.There appeared an increasing trend of hepatitis C reported incidence in China,with most of the high reported incidence of hepatitis C fell in the northern parts of China.74.8％ of the HCV/HIV co-infected cases had histories of intravenous drug use,plasma donation,blood transfusion or surgical operation.Conclusion The reported number and incidence of HCV infection had been increasing annually.To develop a more realistic control measures for hepatitisv C,it is necessary to strengthen the monitoring program and carrying out specific epidemiological study among target groups and key areas.
