Some schools shut and curbs imposed on public gathering in Kerala after two people died of Nipah, a virus from bats or pigs that causes deadly fever.
The virus has no vaccine and a fatality rate ranging from 40 to 75 percent, according to the World Health Organization.
Symptoms include intense fever, vomiting and a respiratory infection, but severe cases can involve seizures and encephalitis, an inflammation of the brain, and result in a coma.
The Nipah virus strain seen in the state was the Bangladesh variant that spreads from human to human and has a high mortality rate, though it is less infectious, the government said. “People living in forest areas have to take the highest precautions,” George had said, adding that the latest case of the Nipah virus originated within five kilometres of a jungle area.
In the wake of the rising Nipah virus cases, neighbouring Tamil Nadu state announced that travellers coming from Kerala would be subjected to medical tests and those with flu symptoms would be isolated.
700 people including 153 health workers who came in contact with those infected are under observation, health officials said.
