Objective To analyze the epidemiological characteristics of measles epidemics in Changsha County from 2007 to 2010 and the incidence of measles vaccine before and after intensive immunization. To explore the strategy of accelerating the control of measles and provide a scientific basis for making prevention and cure measures. Methods Descriptive epidemiological methods. Results 234 cases of measles were reported in 2007-2010. The incidence of infants was less than 8 months old, over 7 years old and floating population. The incidence in urban area was significantly higher than that in rural areas (χ2 = 129.93, P <0.05). No history of immunization or immunization history was found in 81.2% of cases. The incidence of measles vaccine decreased significantly after immunization (χ2 = 132.62, P <0.05). Conclusion The routine immunization of measles vaccine is not the main reason for the incidence of measles, and the effect of intensive immunization is obvious.
