Kerala's Deadly Summer: Snakes Strike Amidst Heat

Kerala has witnessed a disturbing rise in snakebite deaths this summer, with six fatalities reported in the week of April 20-26, 2026. This critical period saw deaths across six districts, including Thiruvananthapuram, Thrissur, Alappuzha, Kannur, and Idukki.

Experts attribute this surge to intense summer heat forcing snakes into human dwellings. The breeding season also coincides with this period, escalating the potential for dangerous encounters between humans and venomous species.

Hospitals are facing challenges in treating snakebite victims, particularly concerning severe allergic reactions to antivenom, which require advanced intensive care. India's polyvalent antivenom is also limited, as it does not cover the venom of the increasingly implicated hump-nosed pit viper.
