The average incidence rate of males was 4 118.81/105， and that of females was 2 930.87/105. The gender ratio （male︰female） was 1.41∶1， with statistical significance （P<0.001）. The intestinal infectious diseases mainly occurred in children aged one to four years old， accounting for 79.09%， and the respiratory infectious diseases mainly occurred in children aged four to six years old， accounting for 63.46%. The incidence and spectrum of NID varied in different age groups. The main population affected was those children from kindergartens， which accounted for 55.46% of all cases.
