EPIDEMIOLOGICAL SURVEY OF VIRAL HEPATITIS OF ONE TROOP.

Objective:To acknowledge epidemiological characteristics and serotypes of viral hepatitis and provide basis for troop's precaution.Methods:Collecting the epidemic situation and related data,and sera of hospital cases from January 1995 to December 2000,using ELISA or RIA detect infected indexes and serotypes of various hepatitis types.Results:The year incident rates of troop's hepatitis changed from 0 65‰ to 1 06‰ in recent years.In hospital cases of acute viral hepatitis,hepatitis A occupied 46 24%;hepatitis B,33 33%;hepatitis C,3 22%;hepatitis E,1 08%;two type hepatitis co or superinfection occupied 2 15%,the cases that all detecting markers of hepatitis were negative occupied 13 98%,acute Jaundice hepatits occupied 50%.In 23 hospital cases of Chronic Viral hepatitis,hepatitis B occupied 73 19%.The acute hepatitis cases were mainly soldiers,and the chronic cases were mainly cadres.Conclusions:In precaution of troop's hepatitis,emphasis should be paid on hepatitis B,and in the same time,precaution measures to hepatitis A should be reinforced as well.
