The virus, first detected in Malaysia in 1998, is spread through infected bats’ fluids or an infected patient’s body fluids. It has an average fatality of around 75 percent, and symptoms include body aches, fever, vomiting and even encephalitis.

Those who recover from the virus may be prone to relapse.

“This is a new situation for us,” the state’s health minister, K.K. Shailaja, told Reuters. “We have no prior experience in dealing with the Nipah virus. We are hopeful we can put a stop to the outbreak.”

“It will not spread like wildfire because it is not airborne, but it can be risky if they don’t follow proper infection control procedures,” Dr. D Himanshu, of King George’s Medical University in Lucknow, told Reuters.

Investigators reportedly are zeroing in on a specific well in Kerala that the victims drew water from. Samples from bats found in the well were sent to laboratories to be screened for the virus, Reuters reported. Kerala officials are also expected to issue a travel advisory for the region.
