New Delhi: In order to stop the spread of the deadly Nipah virus, which has already claimed the lives of two people in the southern state of Kerala, Indian authorities have implemented mass testing. Since 2018, there have been four outbreaks in the region. Nipah is a rare but dangerous bat-borne virus that can make people sick with fever, vomiting, and respiratory infections. Seizures and encephalitis, an inflammation of the brain, can occur in severe cases and put a patient in a coma. The ICMR stated that the virus has a mortality rate of between 40 and 75 per cent.
