The incidents with 1 to 2 cases and 1 death were predominant, accounting for 35.79% and 48.77% of the total number of incidents, respectively.

Yunnan, Sichuan, and Guizhou were the provinces with higher incidence of poisonous mushroom poisoning, with the reported incidents accounting for 35.79%, 16.32%, and 10.70% of the total, respectively. Self-picked poisonous mushrooms were the main source of poisoning, which accounted for 91.75% of the total number of incidents. The occurrence place of the incidents was mainly households, which accounted for 86.67% of the total number of incidents. Twenty-four species of poisonous mushrooms were identified through the surveillance reports, of which Amanita (Amanitaceae) caused the highest number of poisonous mushroom poisoning incidents, poisoning, and deaths, which accounted for 23.86%, 18.03%, and 31.46% of the total, respectively.
