Epidemiological features of acute hemorrhagic conjunctivitis cases in Shi-fang city of Si-chuan province from 2006 to 2010

目的分析2006—2010年四川省什邡市急性出血性结膜炎（AcuteHemorrhagic Conjunctivitis，AHC）病例流行病学特征，为防控措施调整提出建议。方法采用SPSS软件，分析什邡市AHC散发病例和暴发疫情流行病学特征。结果2006—2010年，什邡市累计报告1899名AHC病例，患者职业主要为农民和学生，年龄1天～91岁（平均年龄29．51±19．03岁），男女性别比1．46：1，均为本市感染病例。病例多在发病0-2天内就诊（89．78％，1705／1899）。2006—2009年什邡市AHC发病水平平稳（AHC发病率〈5／10万），2010年出现AHC发病高峰（发病率412．51／10万，为2009年的192．76倍）。发病率居前三位的乡镇分别为禾丰镇（1972．52／10万，近郊）、冰川镇（1075．27／10万，农村）和师古镇（885．04／10万，农村）。结论2010年什邡市AHC流行达到高峰，病例职业以农民和学生为主，建议每年AHC流行前对高危人群开展健康教育，以降低发生AHC暴发和流行的风险，此外还应开展AHC病原学监测。
