Objective To explore the epidemiological characteristics and treatment outcomes of venomous snake bites in Yunnan Province from 2023 to 2024.Methods A retrospective analysis was performed on 1,727 snakebite cases collected from 16 administrative regions in Yunnan Province between January 2023 and December 2024,focusing on the following indicators:(1)demographic characteristics(age and gender distribution);(2)characteristics of injury events(location,time distribution,and affected body parts);(3)composition of venomous snake species;(4)clinical features and treatment protocols;(5)efficacy evaluation indicators(time for local symptom relief,duration of hospital stay,and follow-up results).Results High-incidence areas for snake bites in Yunnan Province included Wenshan(308/1727),Kunming(285/1727),Qujing(270/1727),Lincang(139/1727),Baoshan(120/1727),and Dali(105/1727),with incidents primarily occurring from June to September.The most frequently encountered venomous snake species were Ovophis and Trimeresurus,known for their hemotoxic venom.Bite victims were mainly young adults.Clinical manifestations primarily included pain and swelling,with bites mainly occurring on limbs and in mountainous or forested areas.Anti-venom treatment concentrated on anti-ancistrodon acutus serum.Swelling generally subsided within 2(2,3)days,with an average hospital stay of 4(3,5)days.96.46%of patients receiving standardized treatment fully recovered,with a follow-up disability rate of 0.35%.Conclusion The incidents of venomous snake bites in Yunnan Province have significant regional and seasonal concentration,with Wenshan,Kunming,Qujing and other areas being high-risk areas.The peak period of incidents is from June to September in summer,and the main types of snakes causing injuries are those containing blood toxins;The victim group is mainly young people,and bites often occur in the limbs,with typical symptoms of pain and swelling;The main treatment is anti snake serum;Snake bite patients who receive formal diagnosis and treatment have a higher recovery rate and a lower follow-up disability rate,but there is still a need to raise public awareness of standardized diagnosis and treatment for snake bites.
