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.
