Outline of Final Research Achievements

Results obtained are as follows; 1. We investigated the seasonality of tuberculosis in Wuhan, China, to evaluate the increased risk of disease transmission during each season and to develop an effective TB control strategy. On the basis of results obtained, we suggested that, for summer peaks of SSP, summer influenza epidemics contribute to the increase in TB prevalence (2014); 2. By using surveillance data of chickenpox in Japan and that of hand-foot-and-mouth disease, we proposed a method to investigate the correlation of infectious disease epidemics with meteorological phenomena (2015a, 2015b); 3. We investigated the seasonality of age-specific tuberculosis with monthly age-specific numbers of newly registered cases of active tuberculosis in Japan (2016); 4. We investigated correlation of temporal patterns of reported numbers of admitted patients of both dengue fever and leptospirosis with meteorological conditions [temperature, relative humidity, and rainfall] (in preparation).
