目的评价2009-2013年腾冲县麻疹防控策略的效果,为进一步控制和消除麻疹提供依据。方法收集腾冲县含麻疹成份疫苗(Measles-Containing Vaccine,MCV)接种率、人群麻疹抗体水平和麻疹监测系统相关资料,应用描述流行病学方法综合评价预防控制麻疹的效果。结果 2009-2013年腾4307冲县常规免疫MCV1、MCV2报告接种率和调查接种率分别为98.92、99.21%%和99.41%、97.89%,SIAs及查漏补种报告接种率和调查接种率为98.41%和99.17%,二类麻腮风减毒活疫苗(Measles,Mumps and Rubella combined Attenuated Live Vaccine,MMR)接种率为71.13%,人群麻疹抗体平均阳性(≥1∶250)率96.77%,保护性抗体阳性(≥1∶800)率83.61%,2009年发病率0.16/10万,2010-2013年无本地病例报告,输入性病例2012年发生5例,2013年发生1例。结论将常规免疫接种维持在较高接种水平基础上适时进行MV SIA,并进一步提高接种质量、接种及时率以及加强监测、评估、管理和督导是保障消除麻疹目标实现消除麻疹的根本途径。
Objective To evaluate the effect of measles prevention and control strategies in Tengchong County from 2009 to 2013 and provide basis for further control and elimination of measles. Methods Measured-Containing Vaccine (MCV) inoculation rate, measles antibody level and measles monitoring system were collected in Tengchong County. The epidemiological method was used to evaluate the effect of measles prevention and control measles. Results The reported immunization rates of MCV1 and MCV2 from 2009 to 2013 were 98.92, 99.21% and 99.41%, 97.89%, respectively. The vaccination coverage rate and investigation coverage of SIAs and vaccination coverage were 98.41 % And 99.17% respectively. The vaccination rate of Measles, Mumps and Rubella combined with Attenuated Live Vaccine (MMR) was 71.13%. The average measles antibody positive rate (≥1: 250) was 96.77% The prevalence of antibody positive (≥1: 800) was 83.61%, and the incidence in 2009 was 0.16 / 100000. There was no local case report in 2010-2013. There were 5 imported cases in 2012 and 1 in 2013. Conclusions It is the fundamental way to ensure measles elimination to achieve measles elimination by keeping MV SIA in a timely manner based on higher vaccination level and further improving inoculation quality, vaccination timely rate and strengthening monitoring, assessment, management and supervision.
