Dr Saurab Kumar, associate professor in the GMCH Bettiah’s paediatrics department, told The Telegraph: “I received the child active and alert but his mouth and face was swollen because of the reaction to the venom in the oral cavity.

“We were surprised and cross-checked with his parents multiple times to ensure the child was not bitten by the cobra to rule out that venom had not gone into his bloodstream. They told us he bit the cobra and the snake died on the spot.”

He continued: “The child had eaten a part of the cobra and the venom had gone into his digestive tract, unlike in the cases where the cobra bites the person and venom goes into blood and triggers neurotoxicity.

“We gave him anti-allergy medicine and kept him under watch. As he didn’t develop any symptoms for 48 hours, we discharged the child on Saturday.”

Dr Kumar said the cobra had died apparently because of the trauma to the head and mouth from the child’s bite.

"Seriously we triple checked like 8 times, in our medical opinion, that kid just fucking mashed him."
