Introduction: World Health Organization considers snakebite envenoming as priority neglected tropical diseases. India contributes to 50 per cent of the estimated deaths due to venomous snakebites globally. People from rural areas still believe on traditional healers instead of hospitalisation. Objectives: To depict the socio-demographic analysis of fatal snakebite envenomation by examining medicolegal autopsy in a government medical college in Kolkata, West Bengal. Methods: Total 125 hospitalised snake bite cases with fatal outcome, undergoing autopsy were examined. Sex, age, occupation, socio-economic status of the victims, seasonal variation, time and site of the bite was noted in proforma and analysed. Results: Males, engaged in agricultural activities were mostly the victims who suffered snake bites on their lower limbs in most of the cases. Cases increase in monsoon season. Snake bites occur in highest numbers during the daytime between 6 AM12Noon. Amongst the identifiable species, Krait was responsible for most of the fatalities.37.6% of victims died within the first day, while another 50% died within two weeks after the snakebite. More than 80% of victims were taken to a local therapist/ quack before they were hospitalized. Only 10 patients (8%) were brought within 3 hours after snakebite, while 48% (60) patients were hospitalized within 3-6 hours after the bite and in 15 cases (12%), more than 12 hours elapsed between snakebite and hospitalization. Conclusion: Fatality due to snake bite is preventable. Use of protective gears while working in the field, quick hospitalisation after a snake bite and timely administration of Anti Snake Venom can prevent or reduce its morbidity or mortality.
