2012-2017年山东省菏泽市流行性感冒疫情特点与病毒类型监测结果
|
摘要
目的了解2012-2017年菏泽市流行性感冒(简称流感)疫情特点与病毒类型,指导菏泽市流感防控工作。方法利用"中国疾病预防控制信息系统"选取2012-2017年菏泽市流行性感冒监测病例,对流行性感冒疫情的三间分布特征及流行性感冒病毒病原学特点进行描述性分析。流行性感冒病毒的分离和鉴定采用细胞培养方法。结果 2012-2017年菏泽市共报告流感病例4 014例,年均发病率7. 94/10万;采集1 334例流感样病例咽拭子标本,检出流感病毒329株,阳性率为24. 66%。共监测到H3N2亚型、BY型、BV型和新甲H1N1型4个病毒类型。结论 2012-2017年菏泽市流感疫情相对稳定,流感流行主要集中在冬春季,县区分布、年龄分布、月份分布均不平衡,每年的优势流行株均不相同,先后以H3N2型、BY型、H3N2型、BV型为优势株。为预防流感疫情的发生,今后要加强流感疫苗接种,是预防流感最有效的方式。要扩大流感监测范围,不断提高流感防控水平。
Objective To know the epidemic characteristics and virus types of influenza in Heze during 2012 and 2017,and to guide the prevention and control of influenza. Methods The "China Disease Prevention and Control Information System" was used to select the influenza surveillance cases in Heze City from 2012 to 2017. The three distribution characteristics of influenza epidemic situation and the pathogenic characteristics of influenza virus were descriptively analyzed. A cell culture method were used for the isolation and identification of influenza virus. Results From 2012 to 2017,a total of 4 014 cases of influenza were reported,with an average annual incidence of 7. 94/100 000 in Heze. 1 334 cases of swine swabs were collected,and 329 strains of influenza virus were detected. The positive rate was 24. 66%. Four influenza viruses including H3N2,BY BV and new A/H1N1 were detected. Conclusion The epidemic situation of influenza in Heze City is relatively stable. The influenza epidemic situation in Heze City is mainly concentrated in winter and spring. The distribution of county,age distribution and monthly distribution were unbalanced. The dominant epidemic strains are not the same every year,successively in H3N2 type,BY type,H3N2 type,BV type. In order to prevent the outbreak of influenza,it is the most effective way to prevent influenza in the future. It is necessary to expand the scope of influenza surveillance,and constantly improve the level of influenza prevention and control.
