Nipah virus (NiV) is an emerging zoonotic virus (a virus transmitted to humans from animals).
Nipah virus was first recognized in 1999 during an outbreak among pig farmers in, Malaysia. No new outbreaks have been reported in Malaysia since 1999.
It was also recognized in Bangladesh in 2001, and nearly annual outbreaks have occurred in that country since. The disease has also been identified periodically in eastern India.
Other regions may be at risk for infection, as evidence of the virus has been found in the known natural reservoir (Pteropus bat species) and several other bat species in a number of countries, including Cambodia, Ghana, Indonesia, Madagascar, the Philippines, and Thailand.
It's 40-75% fatal and the way it kills is via encephalitis. There is NO treatment or vaccine at all.

I decided to post this because of Whitney Dafoe and the encephalitis reference. And the timing fits. I feel like I'm grasping at straws, but also I feel like I'd be a jerk if I didn't say anything.
