It is recently found in the Kozhikode district in Kerala.
It is a zoonotic virus caused by the fruit bats.
Human beings can get infected if they come in close contact with the infected animal — bats or other animals such as pigs — or its body fluids such as saliva or urine.
The initial jump of the virus from animal to human is known as a ‘spill over’ event in an outbreak.
Once the infection has moved to humans, person-to-person the spread of virus can occur.
It can also be transmitted through contaminated food, or directly between people.
In India, the outbreaks have so far been limited to West Bengal and Kerala.
