          Abstract

          Objective To grasp the epidemic characteristics of aconite poisoning in Yunnan province from 2012 to 2019, and we provide the basis for formulating prevention and control measures.

          Methods We used the monitoring and reporting system of foodborne disease outbreaks, collecting the data of aconite poisoning events from 2012 to 2019, and the statistical analysis was conducted from the basic situation, the incidence trend, the time distribution, regional distribution, location distribution, poisoning causes and other factors of aconite poisoning.

          Results Aconite poisoning increased year by year, from 6 cases in 2012 to 67 cases in 2019, and the number of incidence increased from 48 persons in 2012 to 308 persons in 2019. A total of 273 cases of aconite poisoning were reported in the past 8 years, including 1 499 persons and 65 deaths. The cumulative morbidity, mortality and fatality rate were 3.12/100 000, 0.14/100 000 and 4.34%. The average number of patients per incident was 5. And 45.79% of the reported incidents were mainly concentrated in October to December; the top five cities were mainly concentrated in Chuxiong prefecture(78), Dali prefecture (40), Baoshan city (30), Qujing city (22) and Yuxi city (21), 60.07% cases of 273 reported incidents occurred in rural areas, 252 cases (92.31%) were family outbreaks, and main reason of the incident was the improper processing of the aconitum plants(82.05%).

          Conclusion Our province should take aconite poisoning as the focus of foodborne disease prevention and control, strengthen knowledge publicity before winter, and conduct health supervision on rural families.
