目的了解深圳市宝安区流行性乙型脑炎(乙脑)的流行情况,为乙脑的预防控制提供科学依据。方法利用传染病报告系统和乙脑监测系统报告数据,分析深圳市宝安区1990-2007年乙脑流行特征。结果深圳市宝安区1990-2007年共报告乙脑病例59例,死亡7例,乙脑年发病率为0～0.664/10万。乙脑发病集中在6-7月,占总病例数的86.40%;病例以散居儿童为主,≤9岁病例占86.40%;2003年以来的病例中66.60%的病例无免疫史或免疫史不详。结论预防控制乙脑应以抓好乙脑疫苗常规免疫接种为根本,建议每年在乙脑流行季节前开展乙脑疫苗查漏补种,重点做好农村和城郊地区的防蚊灭蚊工作,同时加强实验室监测。
Objective To understand the prevalence of Japanese encephalitis (JE) in Bao’an District of Shenzhen City and provide a scientific basis for the prevention and control of JE. Methods The epidemiological characteristics of Japanese encephalitis from 1990 to 2007 in Bao’an District of Shenzhen City were analyzed using the reporting system of infectious diseases and the monitoring data of JE. Results A total of 59 JE cases and 7 deaths were reported from 1990 to 2007 in Bao’an District of Shenzhen City. The incidence of JE was 0 ~ 0.664 / 100 000. The incidence of Japanese encephalitis concentrated in June-July, accounting for 86.40% of the total number of cases; the cases were mainly diaspora, accounting for 86.40% of cases ≤9 years; 66.60% of the cases since 2003 had no history of immunization or immune history . Conclusions The prevention and control of Japanese encephalitis should take the routine immunization of Japanese encephalitis vaccine as the basic principle. It is suggested that the encephalitis vaccine should be leak-checked and replanted annually before the season of Japanese encephalitis, and the anti-mosquito and mosquito control should be done well in rural and suburban areas. Strengthen laboratory monitoring.
