目的分析揭阳市2011-2013年麻疹病例流行病学特征,评价麻疹监测系统运转状况,为进一步防控麻疹疫情提供科学依据。方法汇总揭阳市各县(市、区)上报的2011-2013年麻疹病例监测数据,采用描述性流行病学分析方法,对3年的麻疹病例流行病学特征和免疫学结果进行统计分析,评价监测系统运转的各项指标。结果 2011-2013年揭阳市共报告167例麻疹病例,其中实验室诊断病例155例,临床诊断病例12例,排除病例发病率分别为0.29/10万、2.57/10万和2.18/10万,无死亡病例,无暴发疫情发生,发病时间集中在6-8月,发病人群以8个月~14岁年龄组和无麻疹成分疫苗免疫史或免疫史不详为主。近3年揭阳市麻疹监测系统运转指标逐年提高,2012-2013年监测系统及时性和特异性指标均超过90%。结论揭阳市部分地区常规免疫工作仍存在薄弱环节,应强化常规免疫基础,适时开展查漏补种,做好疫点应急接种,不断提高监测系统的敏感性。
Objective To analyze the epidemiological characteristics of measles cases in Jieyang from 2011 to 2013, assess the operational status of measles surveillance systems and provide a scientific basis for further prevention and control of measles epidemics. Methods The surveillance data of measles cases from 2011 to 2013 reported by counties (cities and districts) in Jieyang City were summarized. The epidemiological characteristics and immunological results of measles cases were statistically analyzed by descriptive epidemiological analysis. The indicators that monitor the functioning of the system. Results A total of 167 cases of measles were reported in Jieyang from 2011 to 2013, of which 155 cases were laboratory diagnosed and 12 cases were clinically diagnosed. The incidences of the cases were excluded were 0.29 / 100000, 2.57 / 100000 and 2.18 / 100000 respectively Deaths, no outbreaks occurred, the onset time concentrated in June-August, the incidence of the population to 8 months to 14 age groups and non-measles vaccine immunization history or history of immunization is unknown. In recent 3 years, Jieyang City measles monitoring system operating indicators increased year by year, 2012-2013 monitoring system timeliness and specificity indicators are more than 90%. Conclusion There are still some weak links in routine immunization work in some areas in Jieyang City. The basis of routine immunization should be strengthened, leak detection and replanting should be carried out in time, emergency vaccination should be done well and the sensitivity of monitoring system should be continuously improved.
