Abstract Objective: To analyze the epidemic characteristics and treatment effect of varicella public health emergencies in Chengde City in recent 15 years, and to provide scientific basis for improving the comprehensive ability to deal with varicella outbreaks. Methods: The public health emergencies of varicella reported in Chengde City from 2006 to 2021 were analyzed descriptively. Results: A total of 70 varicella public health emergencies were reported in Chengde from 2006 to 2021, accounting for 43.48% of the public health emergencies of infectious diseases in the same period. The number of reported cases was 2131, with an average incidence rate of 3.47% and a sex ratio of 1.34∶1. The age of onset was mainly from 7 to 12 years old, accounting for 85.83%. 28.53% of the cases received varicella vaccine; the occurrence was seasonal and bimodal, mainly concentrated in April-June (44.29%) and October-December (45.71%). There were significant differences in the reports of public health emergencies involving varicella in the 11 counties (cities and districts) of Chengde City. Chengde County had the largest number of reported incidents (17 cases, accounting for 24.29%), while Longhua County had no related incidents. All 70 incidents occurred in schools, mainly in rural primary schools (37 cases, 52.86%). The average reporting time was 6 days and the longest was 43 days. The average event duration was 20 days, and the reporting timeliness was positively correlated with the event duration (r=0.362, P<0.05). Conclusion: Most of the public health emergencies of chickenpox occurred in schools and rural primary schools in Chengde City in the past 15 years, and the number of people vaccinated with chickenpox vaccine was relatively low. It is suggested to strengthen the prevention and control of chickenpox epidemic in rural primary schools, improve the active and passive surveillance capabilities and the sensitivity of epidemic detection, improve the level of chickenpox vaccination among school-age children, and establish an effective immune barrier.
