Abstract:
Objective To conduct an epidemiological analysis on the incidence of varicella in Jiading District, Shanghai from 2016 to 2021, and to provide theoretical strategies for the prevention and control of varicella. Methods The data of reported cases of varicella from 2016 to 2021 were collected, and descriptive epidemiological methods were used to analyze the area, time, age and occupational distribution of varicella. Results During 2016-2021, 7261 cases of varicella were reported in Jiading District, including 3993 males and 3268 females. The ratio of male to female incidence was 1.05:1, and the incidence was not statistically different. Anting Town had the largest average annual incidence cases of 227. Malu Town had the highest average annual incidence rate of 92.29/100 000. Varicella occurred every month in Jiading District, of which the peaks were from June to August and from November to January of the following year. The incidence of varicella had periodicity and seasonality, showing “double peaks”. According to the age of onset, the top three groups with the largest number of cases were 0-5 years old group, 6-10 years old group and 26-30 years old group. According to the occupational distribution, the top three groups were students, scattered children and kindergarten children. Conclusion It is necessary to further strengthen the active monitoring of the varicella epidemic and take comprehensive measures to prevent its outbreak. At the same time, it is necessary to increase publicity efforts to improve the vaccination rate of school-age children.
