摘要
目的分析中国2021-2022年麻疹流行特征。方法利用中国麻疹监测信息报告管理系统收集2021-2022年麻疹发病数据,描述性分析发病率和发病特征。结果中国2021年、2022年麻疹报告发病率分别为0.392/100万(552例)、0.391/100万(552例),报告病例县比例分别为13.50%、12.21%。在所有病例中,<8月龄、8-59月龄、5-14岁、15-24岁、≥25岁分别占3.08%、65.94%、10.33%、4.17%、16.48%。在8-23月龄、2-19岁病例中无含麻疹成分疫苗(Measles-containing vaccine,MCV)免疫史比例分别为6.88%(39/567)、0.66%(2/302)。7例病例检出麻疹病毒A基因型(疫苗株),且发病前14 d内均有MCV免疫史。结论2021-2022年中国麻疹报告发病率持续下降;需继续维持适龄儿童2剂次MCV高覆盖率,加强麻疹主动监测和实验室监测。
Objective To describe epidemiological features of measles in 2021-2022 in China.Methods We used the China Measles Surveillance System to obtain data on measles cases reported during 2021-2022 for a descriptive analysis of incidence.Results The incidence of reported measles per million population in China was 0.392(552 cases)in 2021 and 0.391(552 cases)in 2022;13.50%and 12.21%of counties reported cases,respectively;<8-month-olds,8-59-month-olds,5-14-year-olds,15-24-year-olds,and≥25-year-olds accounted for 3.08%,65.94%,10.33%,4.17%,and 16.48%of all cases.Measles cases who had not received measles-containing vaccine(MCV)accounted for 6.88%(39/567)of 8-23-month-old cases and 0.66%(2/302)of 2-19-year-old cases.Measles virus genotype A(vaccine strain)was detected in 7 cases who had received MCV within 14 days before onset.Conclusions The incidence of measles was very low in China during 2021-2022.It is necessary to maintain high coverage with two doses of MCV among age-eligible children and to strengthen active and laboratory surveillance for measles.
