The World Health Orgnization (WHO) on Tuesday said that no fresh cases of the deadly Nipah virus have been detected since September 15 in India’s southern state of Kerala.

In its sixth outbreak in the country since 2001 this year, the virus, known for its 70 percent mortality rate, has claimed two lives out of the six who were infected in a span of few days in September, sending the state government scrambling to contain the spread.
