河北省1997年某山区农村甲肝暴发分析

An Outbreak of Hepatitis A in aMountain Village of Hebei Province

  • 摘要: 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。
