The results showed that ARI incidence rate in the children aged 0-7 years was 348.3%. Most of the cases were upper respiratory infectious. The incidence rate of pneumonia was 2.7%. The relationship between ARI incidence rate and age group showed that incidence of URI of 0-2 age group was 1.5 times higher than that of 5-7 age group, while the incidence of LRI of that 0-2 age group was 6.3 times higher than the later age group. The peak season of ARI was from October to January each year. The virus infections showed its priority in ARI. Duplicate samples of sera of 240 cases were tested.
