目的分析实施网络直报以来广州市急性出血性结膜炎(AHC)的疫情动态,掌握其流行现状,为疫情预测和防控提供科学依据。方法对2005—2011年广州市疾病监测信息报告管理系统中AHC疫情资料进行描述性流行病学分析。结果 2005—2011年广州市共报告AHC病例18 724例,年平均发病率24.08/10万,其中2007年(发病率为33.00/10万)和2010年(发病率为124.32/10万)出现明显高峰;病例集中在夏秋季节的8—10月份,在2007年和2010年8—10月份发病数分别占当年病例总数的96.40%和98.61%;城乡结合部为高发区(33.34/10万),其次是农村地区(18.95/10万)、市区(18.13/10万);病例男女性别比为1.32∶1;各年龄组均有病例报告,但以5～9岁年龄组及0～4岁年龄组发病率为最高,发病率分别为78.64/10万、70.93/10万;职业构成比居前3位的依次为学生(27.60%)、工人(12.85%)、幼托儿童(10.59%)。结论 2005年以来广州市AHC隔2～3年流行1次,且流行强度有增加的趋势,加强城乡结合部和农村地区的AHC疫情监测,做好学校、托幼机构和工厂AHC防治知识、良好卫生习惯的宣传教育是未来控制广州市AHC暴发和流行的重要环节。
OBJECTIVE: To analyze the epidemic situation of acute hemorrhagic conjunctivitis (AHC) in Guangzhou since the implementation of the network direct reporting and to grasp the epidemic situation so as to provide a scientific basis for the prediction and prevention of the epidemic. Methods Descriptive epidemiological analysis of AHC epidemic data in Guangzhou Disease Surveillance Information Reporting Management System from 2005 to 2011 was conducted. Results A total of 18 724 cases of AHC were reported in Guangzhou from 2005 to 2011, with an average annual incidence of 24.08 / 100 000, of which 2007 (incidence 33.00 / 100 000) and 2010 (incidence 124.32 / 100 000) were significant The peak incidence of cases was between August and October in summer and autumn. The incidence rates in 2007 and 2010 were 96.40% and 98.61% respectively of the total number of cases in the same year. The urban-rural combination area was high incidence (33.34 / 100000) Followed by rural areas (18.95 / 100000) and urban areas (18.13 / 100000). The male / female sex ratio was 1.32:1. Cases were reported in all age groups. However, in the age groups of 5-9 years and 0-4 years The highest incidence rate in the age group was 78.64 / 100000 and 70.93 / 100000 respectively. Among the top three occupational groups, the occupational composition was 27.60%, worker (12.85%), preschool child (10.59%), . Conclusions Since 2005, AHC in Guangzhou has been prevailing once every 2 to 3 years and the trend of epidemic intensity has been increasing. The monitoring of AHC in urban and rural areas and rural areas has been strengthened. Knowledge of prevention and treatment of AHC in schools, nurseries and factories and factories has been well established.
