What is Nipah virus? What to know about the disease as India faces outbreak

An outbreak of the Nipah virus in the Indian state of West Bengal is raising concern in parts of Asia, leading some airports to implement precautionary health screenings.

So far, five confirmed infections, including among doctors and nurses, have led to a quarantine of 100 people and the hospitalization of others at various medical facilities in Kolkata, according to the Times of India.

Three Thai airports that receive flights from West Bengal have started screening passengers on arrival. Nepal has also begun screening travellers at the Kathmandu airport and land border crossings with India, the BBC reported.

India’s health ministry says 196 people known to have been in contact with the infected individuals have tested negative, according to the outlet.

What is Nipah virus?

Nipah virus, which can be deadly, is transmitted through several pathways, including from animals to humans — primarily through fruit bats — via contaminated food, or directly between humans and can cause anything from asymptomatic infection to acute respiratory illness and fatal encephalitis, the World Health Organization (WHO) says.

Human‑to‑human transmission occurs through close contact with the bodily fluids of an infected person.

Although the Nipah virus has caused only a few known outbreaks in Asia, it infects a wide range of animals and causes severe disease and death in people, making it a public health concern, according to the WHO.

Infected people generally develop flu-like symptoms such as fever, headaches, muscle pain, vomiting and a sore throat.

Some may experience respiratory issues, including shortness of breath, coughing, and, in more severe cases, pneumonia. This can be accompanied by dizziness, drowsiness and altered consciousness, which may indicate a more complex neurological infection.

The most serious symptoms affecting the central nervous system include seizures, coma and the inability to breathe.

The incubation period is believed to range from four to 14 days, but the WHO has reported an incubation period of up to 45 days.

How deadly is the virus?

Nipah virus has a death rate ranging from 45 to 75 per cent, and there is no vaccine or medical treatment available for animals or humans.

In December 2025, researchers at the University of Oxford, in partnership with the International Centre for Diarrhoeal Disease Research, Bangladesh, launched the world’s first phase two clinical trial of a Nipah virus vaccine involving 306 healthy participants aged 18 to 55.

Most people who survive acute encephalitis, an inflammation of the brain tissue, make a full recovery, though the WHO has reported long-term neurologic conditions in survivors.

Some may also develop meningitis.

Approximately 20 per cent of patients who recover from Nipah virus are left with residual neurological symptoms, such as seizure disorders, and may experience personality changes. A small number of people who recover relapse subsequently or develop delayed-onset encephalitis.

The main course of treatment for humans is supportive care. The virus is described by WHO as a “priority disease” with an “urgent need for accelerated research and development.”

In 2018, at least three people in southern India died after becoming infected with the virus. They were all from the same family.

Where are the outbreaks?

Nipah was first identified during a 1999 outbreak in Malaysia. Since then, outbreaks have been reported in parts of South Asia, including Singapore, as well as in northeast India and Bangladesh. Nipah virus has never been reported or found in Canada.

Nipah virus outbreak in India triggers Asia airport screenings
13 hours ago


The Nipah virus can spread from animals to humans.


An outbreak of the deadly Nipah virus in India's West Bengal state has sparked concern in parts of Asia, with some tightening screening measures at airports.

Thailand has started screening passengers at three airports that receive flights from West Bengal. Nepal has also begun screening arrivals at Kathmandu airport and other land border points with India.

Two cases have been confirmed in West Bengal since December, reportedly in healthcare workers. Some 196 people who were in contact with them have been traced and tested negative for the virus, India's health ministry says.

The virus can spread from animals to humans. It has a high death range – ranging from 40% to 75% – as there is no vaccine or medicine to treat it.

What is the Nipah virus and what are its symptoms?

The Nipah virus can be transmitted from animals, like pigs and fruit bats, to humans. It can also spread person-to-person through contaminated food.

The World Health Organization has described Nipah in its top ten priority diseases, along with pathogens like Covid-19 and Zika, because of its potential to trigger an epidemic.

The incubation period ranges from four to 14 days.

People who contract the virus show a wide range of symptoms, or sometimes, none at all.

Initial symptoms may include fever, headaches, muscle pain, vomiting and sore throat. In some people, these may be followed by drowsiness, altered consciousness, and pneumonia.

Encephalitis, a sometimes-fatal condition that causes inflammation of the brain, may occur in severe cases.

To date, no drugs of vaccines have been approved to treat the disease.



Where were the past outbreaks?

The first recognised Nipah outbreak was in 1998 among pig farmers in Malaysia and later spread to neighbouring Singapore. The virus got its name from the village where it was first discovered.

More than 100 people were killed and a million pigs culled in an effort to contain the virus. It also resulted in significant economic losses for farmers and those in the livestock trade.

Bangladesh has borne the brunt in recent years, with more than 100 people dying of Nipah since 2001.

The virus has also been detected in India. Outbreaks were reported in West Bengal in 2001 and 2007.

More recently, the southern state of Kerala has been a Nipah hotspot. In 2018, 19 cases were reported of which 17 were fatal; and in 2023, two out of six confirmed cases later died.

What is happening now?

India's health ministry said that following confirmation of the cases in West Bengal, contacts of the infected individuals were "identified, traced, monitored, and tested" - and had been found to be asymptomatic.

"The situation is under constant monitoring, and all necessary public health measures are in place," the ministry said.

No cases have yet been reported outside India, but several countries are stepping up precautions.

On Sunday, Thailand started screening passengers at three international airports in Bangkok and Phuket that receive flights from West Bengal. Passengers from these flights have been asked to make health declarations.

The parks and wildlife department has also implemented stricter screenings in natural tourist attractions.

Jurai Wongswasdi, a spokeswoman for the Department for Disease Control, told BBC Thai authorities are "fairly confident" about guarding against an outbreak in Thailand.

Nepal, too, has begun screening people arriving through the airport in Kathmandu and other land border points with India.

Meanwhile, health authorities in Taiwan have proposed to list the Nipah virus as a "Category 5 disease". Under the island's system, diseases classified as Category 5 are emerging or rare infections with major public health risks, that require immediate reporting and special control measures.
