宝安区细菌性痢疾流行病学分析

目的了解深圳市宝安区10年（1995—2004）细菌性痢疾（以下简称菌痢）的流行特征，为制定防治对策提供依据。方法对宝安区1995—2004年疫情资料，作描述性流行病学分析。结果1995—2004年全区菌痢发病率为17．99／10万，无菌痢死亡病例报告，历年发病率波动在9．03／10万-22．40／10万之间，1997年发病率为22．40／10万，是发病率最高的年份，发病率最低是2004年为9．03／10万人，比1995年下降了51．84％。发病年龄以五岁以下儿童及20-30岁之间的青年为主，占总发病数的59．87％，男女性别比为1．21：1；发病职业分布明显，发病率前三位是工人、托幼、散居儿童，占总发病数的72．39％；地区分布以石岩和光明为多；发病季节高峰为夏秋季。结论1995—2004年宝安区菌痢的发病率总体呈下降趋势，防治工作虽已取得显著成绩，但该病发病率一直居于法定传染病百分构成比前五位。综合分析结果，还应进一步加强对重点人群（工人、托幼、散居儿童）及高发季节时段的预防干预。
