目的掌握万州区急性出血性结膜炎分(AHC)布特征和流行病学特点,为制定有效预防措施提供依据。方法利用来自国家疾病监测报告管理信息系统疫情资料,对万州区2006～2010年AHC监测数据进行描述性分析。结果 2006～2010年万州区报告急性出血性结膜炎1286例,年均发病率17.04/10万,其中2010年报告病例908例,发病率59.60/10万。2006～2009年,万州区无聚集性暴发疫情,AHC发病一直处于较低水平,其年度报告发病率均在6.26/10万以内。2010年发生3起学校聚集性疫情。结论 2006～2009年万州区急性出血性结膜炎发病平稳,呈常态散发水平,未发生AHC暴发疫情,2010年发病率是前4年发病平均水平的9倍,提示需加强监测和重点防控。
Objective To understand the characteristics and epidemiological characteristics of acute hemorrhagic conjunctivitis (AHC) in Wanzhou District and provide the basis for effective preventive measures. Methods Using the epidemiological data from the National Disease Surveillance Management Information System, the descriptive analysis of AHC monitoring data from 2006 to 2010 in Wanzhou District was conducted. Results A total of 1286 cases of acute hemorrhagic conjunctivitis were reported in Wanzhou District from 2006 to 2010, with an average annual incidence of 17.04 / 100 000, of which 908 were reported in 2010 with a prevalence of 59.60 / 100 000. From 2006 to 2009, there was no outbreak of cluster outbreak in Wanzhou District. The incidence of AHC was always at a low level, and the incidence of AHC was within 6.26 / 100,000 in each year. Three school-borne aggressions occurred in 2010. Conclusions The incidence of acute hemorrhagic conjunctivitis in Wanzhou District was stable from 2006 to 2009, with normal distribution level and no outbreak of AHC. The incidence rate in 2010 was 9 times of the average level in the first 4 years, suggesting that monitoring and prevention and treatment should be strengthened.
