Abstract:

Objective To understand the epidemiological characteristics of public health emergencies of infectious diseases in the border areas of Yunnan Province in recent years for reference for the prevention and control of the infectious diseases in border areas. Methods The data of public health emergencies of infectious diseases in the border areas of Yunnan Province from 2018 to 2022 were retrieved through the Subsystem of Public Health Emergency Management under the Information System for Disease Prevention and Control in China, and analyzed by descriptive epidemiological methods concerning the temporal and regional distribution. Results In total, 179 public health emergencies of infectious diseases were reported in 25 counties (cities) in the border areas of Yunnan Province from 2018 to 2022, which accounted for 20.53% of the total reported incidents. A total of 14 877 cases and 1 death were reported. Majority of the cases were general incidents (Level Ⅳ) (110 cases, 61.45%), and the main type of cases was Class B infectious diseases (77 cases, 43.02%). Twelve types of diseases were involved, with the top three being novel coronavirus infections (64 cases, 35.75%), chickenpox (42 cases, 23.46%) and influenza (26 cases, 14.53%). The highest incidence of the emergencies appeared between April and July (71 cases, 39.66%), and September and December (65 cases, 36.31%). High incidence occurred in schools (96 cases, 53.63%), in which primary schools accounted for 55.21% (53/96). There were 11 outbreaks caused by imported infectious diseases, of which 7 were from Myanmar (63.64%). The median duration of infectious disease events was 14 (4, 35) days, and the longest duration was 153 days. Conclusion The infectious diseases incidents in the border areas of Yunnan Province are mainly Class B infections diseases, and schools are the key places for prevention and control. At the same time, monitoring and prevention should be strengthened in the high incidence seasons.
