Nipah, is a zoonotic disease, meaning it is spread from animals to humans.

In this case, it appears to have been transferred from fruit bats to humans, via consumption of date palm sap which has been contaminated with a bat’s urine or saliva.

Symptoms can include respiratory difficulties and swelling of the brain, with the virus having a fatality rate of between 40 and 75 percent.

The World Health Organisation (WHO) ranks Nipah as one of its R&D Blueprint priority diseases.
