Epidemiological methods were used to analyze the epidemic situation and epidemiological characteristics of measles in the city. Results The average annual incidence rate of measles was 0.32 / lakh, with no outbreaks and no deaths. The popular measles virus genotype is H1. The distribution of case population was mainly below 8 months old, from 8 months old to 2 years old and above 15 years old, with the proportions of 20.00%, 31.11% and 37.78% respectively; the onset time was concentrated in April and May, accounting for the annual incidence 48.89%; There are 10 county cities and 12 districts in the city have case reports, the annual average incidence of the top three are the Youxian District, Fucheng District and Santai County. 63.16% of cases aged 8 months to 14 years who are under the management of immunization programs have an immunization history of more than 1 dose, and 36.84% of cases have no history of immunization. Infants and children under 2 years of age have been to the hospital before the onset of the disease accounted for 45.45%, the possibility of hospital infection. Conclusion The elimination of measles in Mianyang City was blocked.

Strengthened supervision, supervision and training on vaccine cold chain, vaccine planning and vaccination technology operation.

Strengthen hospital infection control to prevent the spread of the epidemic.
