Kochi: Two students from a private school in Kakkanad in the Ernakulum district tested positive for the Norovirus on Monday. About 62 students from the school showed symptoms similar to Norovirus infection, after which the school sent the samples for testing to State Public Lab. The reports confirmed two of the students to have contracted the virus. The school has meanwhile been shut down for three days to avoid the spread of the highly contagious virus.
