Almost a year after 'Nipah' (NiV) caused panic in Kerala after claiming over 17 lives, the deadly virus is back in the state. On Tuesday, Kerala Health Minister K K Shailaja confirmed that a 23-year-old college has been infected with the Nipah virus in Kochi. The results of blood samples of the student were tested at the National Institute of Virology (NIV) in Pune. The government is preparing a list of people who were in contact with the infected youth. The government has so far listed out at least 86 people who he came in contact with recently. They have been kept under observation and asked to report to the nearest medical facility if they develop influenza-like symptoms like fever, headache, myalgia (muscle pain), vomiting and sore throat.

Health minister Dr Harsh Vardhan told reporters that there is no need to panic, after chairing high level meeting on Nipah Virus in Kerala this morning.

He also said that the wildlife department had been asked to capture bats for testing of the virus.
