Abstract：Objective To analyze the epidemiological features of measles in Fangshan District of Beijing from 2008 to 2021, and to provide a scientific basis for adopting targeted measures to control and eliminate measles. Methods Descriptive epidemiological methods were used to analyze the incidence of measles in Fangshan District of Beijing from 2008 to 2021. Results A total of 498 measles cases were cumulatively reported in Fangshan District during 2008-2021, with an average annual incidence rate of 3.29/100,000. The average annual incidence rate was higher in residents from other provinces (4.89/100,000) than in local residents (2.74/100,000). The incidence rates of measles in 2017-2021 fluctuated from 0/100,000 to 0.76/100,000, and showed a downward trend. The incidence of measles was mainly concentrated inMarch-May, accounting for 66.87% of the total cases. The age at onset showed a bimodal distribution, with peaks in children under 1 year old (with the incidence rate of 104.54/100,000) and adults aged 25-39 years (with the incidence rate of 5.37/100,000). Most of the cases were scattered children, the unemployed and cadres. Among the measles cases aged ≥8 months, 15.89% had immunization history, 30.32% had no immunization history, and 53.79% had unknown immunization history. Among the cases aged 8 months-19 years, the proportion of cases with immunization history was higher in local permanent residents than in floating population from other provinces, showing a statistically significant difference. Conclusion The incidence of measles in Fangshan District during 2008-2021 remained at a low level. It is an effective way to control and eliminate measles by establishing immune barrier for school-age children and encouraging the vaccination of measles containing vaccine in high-risk groups.
