The influenza detection rate was 8.77%. The epidemic peaks appeared from February to April and from July to September, and more than a subtype existed each year. The influenza detection rates appeared a rising tendency with age added （X^2=28.37, P〈0.05）. Conclusion Influenza showed seasonal activity in children.
