What Is Nipah Virus
Nipah virus infection is a highly contagious, lethal disease that has been discovered in Malaysia, Bangladesh, and West Bengal, India. A similar virus, called Hendra virus, was also discovered in Queensland, Australia. Nipah virus is carried by fruit bats.
How Do You Get Nipah Virus?
In countries where palm sap is collected in jars placed in palm trees, infected bats contaminate the sap. Unboiled contaminated palm sap is frequently consumed by humans and can result in infection. The virus can also spread directly from ill patients to caregivers. In other outbreaks, pigs become infected after eating contaminated half-eaten fruit dropped by the bats, and in turn, infect humans that consume the pork.

All people are susceptible. The level of immunity after surviving this disease is not known. There have been some people who survived Nipah virus infection and have been re-infected.
