Inoculation rate and incidence of measles among children were performed by Chi-square test. P≤0.05was considered as statistically significant.Results1. The incidence of measles shown obvious seasonal pattern. The peak season were spring and summer, the most cases in summer. Sporadic and outbreaks exist at the same time.2.

In addition, the positive rate of measles antibody and rate of protection in scattered and foreign residence children is lower than childcare and local household ones (P<0.05).5.
