Epidemiological feature of acute sporadic hepatitis E in four field armies population

AIM To survey the incidence and distribution of acute viral hepatitis E (AHE) in Chinese PLA. METHODS By the method of cluster sampling, a prospective study on the incidence of AHE was conducted in 1993 on a total of 160 360 army personnel, who were stationed in the Northeast, East, Southwest and South of China respectively. From 1st of January to 31st of December in 1993, there were altogether 310 acute viral hepatitis cases. All acute viral hepatitis sera were collected and anti HEV IgM and anti HEV IgG were detected. RESULTS Among all the acute hepatitis cases, there were 38 acute viral hepatitis E cases, which accounted for 12.26%, and the incidence rate of hepatitis E was 23.7/100 000. The AHE incidence of a unit in Jinan ( 28.6 / 100 000 ) was the highest, while that of a uint in Guangdong was the lowest (14.6/ 100 000 ). There were two incidence peaks of AHE: from March to April and from August to November. No significant difference was found in the AHE incidence between commanders and soldiers or recruits and veterans. CONCLUSION Acute hepatitis E is sporadic in army personnel and serious attention should be paid to its prevention.
