Risk of Viral Hepatitis in Different Regions of China and Its Influencing Factors

Objective To evaluate the risk of viral hepatitis in different regions of China and analyze its influencing factors.Methods The incidence of 4 types of viral hepatitis(hepatitis A,B,C,E) in 31 provinces of China were analyzed.Results The Northwest China had the highest incidence of hepatitis A,B,and C,while the East China had the highest incidence of hepatitis E.Qinghai Province,Xinjiang Province,and Gansu Province had the highest risk for infecting hepatitis,while Shandong Province,Tianjin Province,and Hunan Province had the lowest.Hepatitis B and C had similar incidence,which might be explained by their resemblance in etiology,mechanism,and routes of transmission.However,hepatitis A and E significantly differed in incidence.Medical advances had shown effects in the prevention and control of hepatitis A,but not for other three types of viral hepatitis.Conclusion There are regional differences in incidence of viral hepatitis in China,which might be related with the etiology,mechanism,and routes of transmission.
