Objective To find out epidemiological characteristics of measles in Liangxi District during 2015 to lay scientific basis for its elimination. Methods The measles surveillance data in Liangxi District in 2015 were analyzed with descriptive epidemiological methods. Results A total of 70 measles cases were reported in 2015. The peak of incidence was noted from April to May. Children younger than 1 year and the group of people from 20 to 49 years old was the major group affected by measles. Those who had no immunization history and whose immunization history remained unknown accounted for 42.86% and 42.86%, respectively. Conclusion An important factor resulting in measles attack is the lack of adequate immunization for appropriate age groups in the area. Peaks of incidence rates are found in both younger infants and adults, indicating the need for further improvement in the coverage and timeliness of routine immunization of measles vaccines. Measures should be taken to control the incidence among migrant population and adults.
