Objective To analyze the epidemic situation and inoculation of measles in Shishi city from 2005 to 2013 and evaluate the effect of control measures. Methods Descriptive epidemiological methods were used to evaluate measles epidemiology, surveillance system and routine immunization. Results A total of 213 cases were reported in the city from 2005 to 2013, with an average annual incidence rate of 4.23 / 100 000. There was no case from 2010 to 2012, and the incidence rate showed a decreasing trend. The incidence was concentrated in 3 to 7 months (78.4%), with a higher prevalence in urban areas; scattered children in the patients accounted for 56.8%, 0 to 3 years old accounted for 50.7%, floating population accounted for 44.1%; 6 outbreaks were floating population; 0 dose immunization accounted for 43.2%, unknown history of immunization accounted for 38.0%. The complete investigation rate of suspected cases within 48h was 97.6%; the blood sample collection rate was 88.5%, the delivery rate within 3 days was 91.1%, and the timely report rate was 94.0% within 7 days. Conclusion The incidence of measles in Shishi City decreased from 2005 to 2013, and the monitoring of migrant children still needs to be strengthened in order to prevent and control key populations.
