Abstract:
Objective: To understand the epidemiologic characteristics and spatial-temporal distribution of hepatitis E in Shanghai between 2006 and 2016. Methods: The reported incidence of hepatitis E and health facilities' information between 2006 and 2016 were collected from the China Information System for Disease Control and Prevention. The geographic information were from Shanghai Surveying and Mapping Institute. The map scale was 1∶750 000. Global and local autocorrelation, and spatial-temporal detection methods were applied to determine the spatial-temporal characteristics of hepatitis E. Software ArcGIS 10.1 was used to analyze global and local spatial auto correlation of hepatitis E spatial clusters. Software SaTScan 9.4.4 was used to conduct scan for exploring the areas of hepatitis E temporal spatial clusters. Results: A total of 6 048 cases of hepatitis E were reported in Shanghai during 2006-2016. The average incidence was 2.14/100 000. Spatial auto correlation analysis indicated that there was significant spatial positive correlations and spatial-temporal clustering of hepatitis E in Shanghai, and the "high-high cluster" was mainly located in the downtown of the city. Conclusion: Understanding the spatial-temporal clustering areas of hepatitis E cases in Shanghai from 2006 to 2016 is important to the reasonable allocation of public health resources and effective prevention and control of hepatitis E.
