Union Ministry of Health & Family Welfare officers broke into celebrations on Thursday evening when a phone call from the Enterovirus Research Centre, Mumbai, informed them that the suspected case of polio reported from Bihar had tested negative for wild poliovirus.

Earlier in the day, the Ministry went into a tizzy on being informed of the suspected case of polio from Darbhanga, Bihar. Soon, the government declared an immunisation drive in 28 districts of the State as a precaution, while carrying out detailed investigation into the case.
