A 14-year-old boy, who was diagnosed with the Nipah virus, died in Kerala on Saturday, officials said on Sunday.

According to reports, the boy suffered a massive cardiac arrest and could not be revived.

"He was on ventilator support. The urine output had reduced this morning. After a massive cardiac arrest, the revival efforts failed and he passed away at 11.30 am," Kerala Health Minister Veena George told India Today.

The minister said his last rites will be performed as per medial protocols.

A multi- member joint outbreak response team from the National ‘One Health Mission’ of Union Health Ministry will be deployed to support the State in investigating the case, identifying epidemiological linkages, and providing technical assistance.

Additionally, at the State's request, ICMR had sent monoclonal antibodies for patient management, and a mobile BSL-3 laboratory for testing additional samples from contacts has arrived in Kozhikode.

The Monoclonal Antibodies had reached before the patient died but could not be used due to his poor general condition.

"It is important to note that outbreaks of Nipah Virus Disease (NiVD) have been reported in Kerala in the past, with the most recent one occurring in 2023 in the Kozhikode district," read the statement issued by the Indian Ministry of Health and Family Welfare.

How human beings can be infected by the virus?

Fruit bats are the usual reservoir of the virus, and humans can become infected by accidentally consuming bat-contaminated fruits.

The case fatality rate is estimated at 40% to 75%, as per WHO website.

What are the signs of symptoms of the disease?

Human infections range from asymptomatic infection to acute respiratory infection (mild, severe), and fatal encephalitis.

Infected people initially develop symptoms including fever, headaches, myalgia (muscle pain), vomiting and sore throat. This can be followed by dizziness, drowsiness, altered consciousness, and neurological signs that indicate acute encephalitis. Some people can also experience atypical pneumonia and severe respiratory problems, including acute respiratory distress. Encephalitis and seizures occur in severe cases, progressing to coma within 24 to 48 hours, reads the WHO website on the disease.

The incubation period (interval from infection to the onset of symptoms) is believed to range from 4 to 14 days.
