Seventeen people have died in the Indian state Kerala from the Nipah virus (NiV), a disease that causes acute respiratory syndrome and fatal encephalitis (swelling of the brain). There is no vaccine for Nipah virus.

It is spread primarily by fruit bats, and is transmitted to humans “through secretions from the bat to the fruit it feeds on or touches.” According to the CDC, transmission to humans can also occur “after direct contact with infected bats, infected pigs, or from other NiV infected people.” Person to person transmission is commonly seen among family and caregivers of someone infected. Papers report that a nurse who was treating victims recently died of the disease herself.

Fruits and vegetables imported from the state of Kerala have been banned and the UAE Ministry of Health and Prevention has also issued a travel warning. State Health Minister KK Shailaja says that although it seems the first wave of the outbreak may be over, people should prepare for a second wave:

“The presence of Nipah virus can be confirmed only when the affected people show symptoms. So it is very essential for the affected people to be alert till their incubation period is over…The government has made elaborate arrangements to check the spread of the disease and the people who closely engaged with the Nipah infected people should avoid public gatherings and meeting till the end of the incubation period.”
