Russell's vipers, known for their venom, are reappearing in northern and southeastern Bangladesh

Russell's vipers, once endangered in Bangladesh, have seen a significant resurgence in the northern and southeastern regions. Sightings in districts like Rajshahi, Chapainawabganj, and Patuakhali indicate their presence in farms and homes, both adults and young. Their venomous bite induces severe symptoms such as loss of limb control, bleeding, nerve damage, paralysis, and kidney impairment. Dr. Md. Abdul Wahed Chowdhury from the Venom Research Centre suggests that the shift to multi-crop farming in the north attracts rodents, thereby drawing snakes. Dr. Mohammad Firoj Jaman speculates that floodwaters from the Padma River bring snakelets from India during monsoons, settling in regions like Rajshahi and the south, posing risks to farmers and riverbank residents alike.
