The Kerala government has launched an extensive search for the source of the deadly Nipah virus that has staged a comeback in the state after a year.
The virus was found to have spread last year from a 26-year-old youth who contracted it after consuming a fruit bitten by a fruit bat carrying the virus. Though the source of the infection last year was a tiny village near Perambara in Kozhikode district, scientists took three months to identify the carrier of the virus.
