摘要
目的了解中国(未包括香港、澳门特别行政区和台湾地区,下同)2004~2009年甲型病毒性肝炎(甲肝)的流行病学特征,为预防控制甲肝提供流行病学依据。方法利用中国法定传染病报告系统数据,进行甲肝描述性流行病学分析。结果中国2004~2009年甲肝报告发病率分别为7.20/10万、5.61/10万、5.37/10万、5.98/10万、4.34/10万、3.30/10万;报告病例主要集中在河南、四川、云南、贵州、新疆、甘肃省(自治区,下同),6个省甲肝病例数占当年全国总病例数44%~51%。近30%的病例为<15岁儿童,病例主要为农民和学生。2004~2009年报告甲肝突发公共卫生事件主要集在中、小学校,病例主要为在校学生。结论中国2004~2009年甲肝报告发病数(率)逐年下降,表明以甲肝疫苗预防接种为主的预防控制措施成效显著;加强甲肝监测,及时发现、调查、处理甲肝聚集性病例,可有效控制甲肝疫情爆发。
