One Health programme essential for Nipah virus prevention and zoonotic spillover
Kerala has recently detected two Nipah virus cases, including one fatality, highlighting the urgent need for a robust "One Health" programme. Nipah is a highly transmissible viral infection with a mortality rate of 40-75%, making prevention and awareness crucial as there is no effective treatment. Fruit bats are the natural reservoirs, and contaminated fruits are suspected to spread the virus. The article stresses the importance of monitoring climate change-related factors and anthropogenic activities that destroy natural habitats, as these contribute to zoonotic spillover. India has experienced several Nipah outbreaks since 2001, with Kerala regularly reporting cases. A comprehensive One Health approach is needed to address Nipah and other pathogens capable of transitioning from animals to humans.
Key Points
