2013 - 2017年拉萨市麻疹监测情况分析

目的 分析拉萨市麻疹监测工作开展情况，提高麻疹监测工作质量。方法 用描述性流行病学方法对2013 - 2017年拉萨市麻疹监测数据进行分析。结果 2013 - 2017年共报告麻疹监测病例662例，其中麻疹确诊病例497例，排除165例（风疹15例），8月龄以上麻疹病例具有麻疹接种史仅占13.8%。2013 - 2017年以麻疹监测病例个案调查表为数据，48 h内完整调查率为91.0%～100.0%，麻疹监测病例血清学检测结果4 d内报告率为40.9%～72.6%，排除麻疹病例分别占麻疹监测病例的44.4%，34.9%，19.1%，33.3%，23.9%，散发麻疹监测病例血标本采集率分别为98.1%～100.0%，无暴发疫情，麻疹监测工作逐年提高。2014 - 2017年麻疹监测信息系统中48 h内完整调查率仅为29.0～95.7%，检测结果7 d内报告率32.1%，61.3%，41.1%，43.1%。排除麻疹病例仅占监测病例的0～19.9%。血标本采集率为66.3～97.2%。48 h内录入个案率分别为19.4%，31.3%，5.0%，70.1%。结论 应加强预防接种工作，消除免疫空白人群，进一步提高监测工作质量，以适应消除麻疹工作需要。

Analysis on the status of the measles surveillance in Lhasa between 2013 and 2017

Objective The aim of this study was to analyze and understand the status of the measles surveillance in Lhasa from 2013 to 2017. Methods We analyzed the measles surveillance data of MSS statistics in Lhasa and evaluated the performance indicators. Results Totally, 662 suspected measles cases were reported through MSS from 2013 to 2017, of which 497 were classified as laboratory confirmed measles cases and 165 were discarded measles cases. Only 13.8% of the cases had a history of measles vaccination. Accodring to surveillance data from 2013 to 2017, proportions of cases investigated within 48h were 91.0% to 100%, and percentages of serum specimen with laboratory results reported within 4 days were from 40.9% to 72.6%. The proportions of discarded measles case were 44.4%, 34.9%, 19.1%, 33.3% and 23.9%. Proportions of suspected measles cases with adequate serum specimen were between 98.1% and 100%. Without an outbreak, measles surveillance was improving year by year from MSS data. From 2014 to 2017, proportions of cases investigated within 48h were from 29.1 to 95.7 and percentages of serum specimen with laboratory results reported within 7 days were from 32.1% to 61.3%. The proportions of discarded measles case were from 0 to 19.9%. Proportions of suspected measles cases with adequate serum specimen were from 66.3 to 97.2%. Proportions of entry the data into MSS within 48h were 19.4%, 31.3%, 5.0% and 70.1%. Conclusion Improving measles vaccination coverage among population may decrease the measles incidence of population in Lhasa, and it is necessary to improve the work quality to reach the goal of measles elimination.
