Abstract

Abstract

Objective To analyze epidemiological characteristics of measles from 2011 to 2020 in Anhui Province and explore the strategies for measles elimination. Methods The epidemiological characteristics of measles in Anhui Province from 2011 to 2020 were analyzed by descriptive epidemiology. Results A total of 8 892 cases of measles were reported in Anhui province from 2011 to 2020, with an average annual incidence of 1.48/100 000, the overall trend is downward (X²_trend=1 794.80, P<0.001).Measles cases were mainly concentrated from February to June, and there was no obvious seasonal clustering in the years with low incidence.The average annual incidence in northern Anhui, central Anhui and southern Anhui were 1.82/100 000, 1.12/100 000 and 1.24/100 000 respectively, with the difference being statistically significant (X²=44.95, P<0.001).About 90.25% of the total cases were people aged less than 2 years and over 15 years old, 56.94% of the cases had no history of receiving MCV vaccination, and 30.40% don't know if they've been vaccinated.There were 758 cases in which measles virus genotypes were available, including 737 cases with H1 genotype, 16 cases with vaccine strain A genotype, 2 cases with B3 genotype, and 3 cases with D8 genotype.A total of 5 public health emergencies and 76 outbreaks of measles were reported. Conclusions The incidence of measles in Anhui Province decreased from 2011 to 2020 and maintained low in recent years.We should increase MCV coverage and timely vaccination among age-eligible children, conduct MCV supplementary immunization activities if necessary, and enhance epidemiological and etiological surveillance of measles, in order to block the spread of measles effectively.
