There were 66 deaths,and the average annual mortality rate was 0.0807/100 000. The incidence trend showed a "horizontal" fluctuation in the years（P<0.05）,and the peaks appeared April to July and September to October. The incidence in urban areas was significantly higher than that in rural areas（P<0.05）. The high-incidence population were children aged 0-<5 years old,accounting for 81.64%. The main occupation was scattered children,accounting for 62.31%,followed by the preschool care children,accounting for 24.45%.
