Methods Descriptive statistical analysis of the survey data of measles cases in the West Lake from 2004 to 2010 was conducted. Results A total of 481 measles cases were reported in Xihu District from 2004 to 2010, with an average annual incidence of 12.14 / 100 000, up to 21.48 / 100 000 and 37.10 / 100 000 in 2005 and 2008, respectively. The incidence peaked from March to June each year, and the high incidence areas were distributed in Sandun Village and Jiangcun Wensin Sub-district. The proportion of those less than 1 year old, 20-30 years old and 30-40 years old was relatively high, accounting for 28.0% , 26.4% and 20.2% respectively. The children without measles immunization accounted for 58.62% of the children aged from 8 months to 1 year old, and 61.54% of the migrant children without immunization history. Conclusion The annual incidence of measles in the West Lake area fluctuates greatly, with a periodic distribution every year. The combination of urban and rural areas is under the age of one and under the age of one. Those who are over 20 years of age are in high need of routine vaccination and adult intensive vaccination.
