Nipah: The Virus Woken by Climate Change

The Next Pandemic? With a fatality rate up to 75%, the Nipah virus is one of the deadliest pathogens on Earth. And human activity is making it stronger.

Meet the Carrier Pteropus fruit bats are the natural reservoir for Nipah. In the wild, they are harmless. The virus lives in them without making them sick.

Losing Their Home Massive deforestation and environmental degradation in Asia have destroyed the bats' natural habitats. Result: They have nowhere left to go but to us.

Starving & Stressed Climate Change is altering fruiting seasons in the wild. When bats can't find food in the forest due to drought, they migrate to human orchards and farms to survive.

How It Jumps The virus jumps from bats to animals (like pigs) or directly to humans via contaminated food.

In Bangladesh and India, hungry bats drink from date palm sap collection pots at night. They leave behind saliva and urine infected with Nipah, which humans then drink raw.

Research shows that nutritional stress (from climate shocks) causes bats to "shed" more virus load than usual. Key: A stressed bat is a more infectious bat.

No Cure, No Vaccine  Unlike COVID-19, there is currently no approved vaccine for Nipah. Symptoms: It causes severe brain inflammation (encephalitis) and respiratory distress.

As cities expand into forests, the buffer zone disappears. Warning: Nipah outbreaks are becoming more frequent as the gap between wildlife and humans closes.

The best way to prevent Nipah isn't just medicine—it's conservation. Restoring forests keeps bats in the wild and viruses away from us.
