Understanding Nipah: Transmission & Fatality

Nipah is a zoonotic virus—transmitted from bats (fruit bats or pigs) or contaminated food, and possibly via human-to-human contact. It can cause encephalitis, with a fatality rate ranging from 40–75% 4. The World Health Organization considers Nipah a high-priority pathogen due to its potential to trigger outbreaks 5.

Kerala’s History with Nipah Outbreaks

The state has faced multiple Nipah outbreaks: in 2018 (17 deaths), 2021 (one death), and in 2023 (two deaths). From 2018 to 2024, Kerala recorded a total of 21 Nipah-related deaths 6.
