为探讨山区农村甲肝流行特点，对１９９７年发生在河北省某山区农村的甲肝暴发进行了流行病学调查和血清学分析。该村１５年内未发生过甲肝流行，暴发前３个月曾发生２例甲肝，暴发前曾大量降雨，并造成饮用水井淹没。此次暴发始于７月２１日，８月发病达高峰；９月２３日结束，历时６４天，共发生甲肝２３例，１—１４岁儿童发病率１９．３３％（２３／１１９）。经血清学分析，此次暴发新感染者中临床型甲肝占６０．５３％，暴发后１～１４岁儿童遗留易感率为５．７１％。易感者的积累和饮用水污染可能是此次暴发的原因，建议在山区农村改善饮水条件和开展甲肝疫苗预防接种。
In order to explore the characteristics of hepatitis A in mountainous areas in rural areas, epidemiological investigation and serological analysis were conducted on the outbreak of hepatitis A in a mountainous area in Hebei Province in 1997. There was no hepatitis A epidemic in the village within 15 years. Two cases of hepatitis A occurred in the first 3 months of the outbreak. There was a lot of rainfall before the outbreak and drinking water wells were drown. The outbreak began on July 21, August peak incidence; September 23 ended, which lasted 64 days, a total of 23 cases of hepatitis A, 1-14 years old children incidence rate of 19.33% (23/119). Serological analysis, the outbreak of newly infected persons accounted for 60.53% of clinical hepatitis A, 1-14 years after the outbreak of children left the susceptibility was 5.71%. The accumulation of susceptible people and drinking water pollution may be the reason for the outbreak, it is recommended to improve drinking water conditions in rural areas and to carry out hepatitis A vaccine vaccination.
