Abstract：OBJECTIVE To compare and analyze the epidemiological features of measles,mumps and rubella in China from 2010 to 2019.METHODS The incidence data of the three diseases were collected by The Data Center of China Public Health Science,the incidence and features of the three diseases were descriptively analyzed.RESULTS The reported incidence of measles began to rebound at the end of 2012 and reached a peak in 2014,with the reported incidence of 3.88/105,an increase of 90%compared with 2013,and a decrease year by year after 2015.The prevalence of mumps was high in 2011 and 2012,with the reported incidence of 33.89/105 and 35.59/105,respectively.The incidence of mumps showed a downward trend from 2012 to 2016,and then a steady rise from 2017 to 2019.The reported incidence of rubella decreased year by year from 2010 and reached its lowest level in 2017,but the incidence recovered significantly after 2018 and peaked again in 2019.In general,the reported incidence of the three diseases in western region was higher than that in eastern and central regions.In terms of age distribution,measles and rubella cases under the age of 1 year accounted for the highest proportion,more than 50%,and mumps cases were mainly in children over 2 years old.CONCLUSION Measles,mumps and rubella diseases have been effectively controlled in China,but there are still children of appropriate age who have not received or only received one dose of vaccine.It is suggested that while joint prevention and treatment of the three diseases,provinces and cities should formulate scientific and reasonable policies according to local conditions and continue to strengthen immunization coverage.According to the age distribution of the disease,it is recommended to continue to maintain the 2-dose vaccination program for children of appropriate age to enhance immunization coverage.At the same time,the vaccination of children aged 5～9 years with mumps components to reduce the occurrence of clusters of outbreaks in schools.
