Epidemiological characteristics and species analysis of mushroom poisoning incidents in Sichuan Province from 2019 to 2022
Objective The analyze the epidemiological characteristics of mushroom poisoning incidents in Sichuan Province from 2019 to 2022,and provide scientific basis and reference suggestions for the prevention and control of mushroom poisoning in Sichuan Province.Methods Information related to mushroom poisoning in Sichuan Province from 2019 to 2022 was collected from the Food-borne Disease Outbreak Surveillance System.Excel 13.0 was used to organize the relevant data,and the data were analyzed.Results A total of 474 cases of mushroom poisoning were reported in Sichuan Province from 2019 to 2022,with 1 659 cases and 10 deaths,and the case fatality rate was 6.03％o.The period from June to October was a high incidence period for mushroom poisoning incidents,with the number of incidents,incidence,and mortality accounting for 91.77％(435/474),91.56％(1 519/1 659)and 80％(8/10),respectively.Mianyang City,Liangshan Prefecture,Zigong City,Yibin City,Guangyuan City,Chengdu City and Luzhou City were the key cities and prefectures,with the number of incidents and incidence of 81.22％(385/474)and 78.72％(1 306/1 659),respectively.Anzhou District,Yanyuan County,Jiangyou City,Rong County,Youxian District,Wangcang County,Gulin County,Muli Tibetan Autonomous County and Santai County were the key districts and counties,and the number of incidents in these nine districts and counties exceeded 10,accounting for 47.89％(227/474)of the total number of incidents.Families were high-risk places,with the number of incidents,incidence,and mortality accounted for 88.40％(419/474),81.74％(1356/1659)and 100.00％(10/10),respectively.The main cause of the incident was self-mining,accounting for 75.20％(379/504).The main cause of the incident was ingestion and misuse,accounting for 97.28％(465/478).Among the identified toxic types,gastroentertis type was the main type,accounting for 65.45％(36/55).Conclusion Relevant departments should increase project funds to support the identification and typing of toadstool species.Key areas should actively carry out health education activities on mushroom poisoning for key populations during the high incidence season,create local wild mushroom science popularization maps,and carry out wild mushroom education in rural areas and households.Grassroots medical institutions should improve the diagnosis ability and treatment level of mushroom poisoning cases.Relevant departments need to continue to strengthen the construction of the monitoring and reporting systems.
