Nipah Virus Alert: Asian airports tighten health screening after Nipah virus cases in India. Learn about symptoms, how it spreads, and travel safety tips for UAE residents visiting India.
What’s Happening: Nipah Virus Detected in India
Airports across Asia have increased health screening for passengers after Nipah virus cases were detected in India. This is similar to the COVID-style health checks we saw during the pandemic.
Current Situation in India
Health officials in India have confirmed several cases of Nipah virus in West Bengal, a state in eastern India. The virus was first discovered among five healthcare workers who were treating patients.
The good news is that Indian authorities say the situation is contained. This means they believe they have stopped the virus from spreading widely.
Where Cases Have Been Found
Two main areas in India are dealing with Nipah virus:
West Bengal: The current outbreak started here, with cases reported in Barasat, near the city of Kolkata. Officials are investigating 100 to 200 potential contacts (people who may have been exposed).
Kerala: This southern state has dealt with Nipah virus before. It’s considered an endemic region, which means the virus appears there from time to time.
Dr. Sayan Chakraborty, former health advisor for West Bengal, clarified that only two confirmed cases have been reported. Other suspected cases tested negative and those patients have been sent home.
Why This Matters
Even though only a small number of cases have been confirmed, countries are taking this seriously because:
- Nipah virus has a very high death rate (40-75% of infected people die)
- There is currently no vaccine available
- The virus can spread from person to person
- Early detection and quick action are crucial
Dr. Narendra Kumar Arora, President of AIIMS Bilaspur, explained that while monoclonal antibodies (special medicines) are being obtained for treatment, global supplies are very limited.
Containment Measures
People who may have been exposed to the virus must quarantine for 21 days. This mainly affects:
- Family members of infected patients
- Hospital staff who treated them
- Anyone who had close contact with sick people
The 21-day quarantine period is longer than what we saw with COVID-19 (which was typically 10-14 days).
Which Countries Are Taking Action
Several Asian countries have responded quickly by increasing airport health screening and passenger monitoring. Let’s look at what each country is doing.
Thailand’s Response
Thailand is monitoring passengers arriving from West Bengal at three major airports:
- Suvarnabhumi Airport (Bangkok’s main international airport)
- Don Mueang Airport (Bangkok’s domestic airport)
- Phuket International Airport
What Thailand is doing:
- Fever checks for arriving passengers
- Symptom screening (asking about headaches, cough, vomiting)
- Distributing health advisory cards
- Enhanced disease-control measures at airports
These health checks help identify people who might be sick before they enter Thailand.
Nepal’s Response
Nepal shares a long land border with India, so they’re taking extra precautions at both airports and border crossings.
What Nepal is doing:
- Intensified screening at Tribhuvan International Airport (Kathmandu)
- Health checks at key land borders with India
- Health desks set up to manage suspected cases
- Monitoring travelers coming from affected areas in India
Since many people travel between Nepal and India by road, border screening is especially important.
Taiwan’s Response
Taiwan is taking perhaps the most serious approach among Asian countries.
What Taiwan is doing:
- Planning to classify Nipah as a Category 5 notifiable disease
- Category 5 is the highest level for emerging infections
- This requires immediate reporting of any suspected cases
- Strict control measures must be followed
- A Level 2 “yellow” travel alert remains for Kerala, India
A Category 5 classification means doctors and hospitals must report any suspected Nipah cases immediately to health authorities.
Why These Measures Matter
These screening measures help protect public health by:
- Catching sick travelers before symptoms get worse
- Preventing the virus from spreading to new countries
- Giving health workers early warning about potential cases
- Allowing quick isolation and treatment if needed
The screenings also reassure the public that governments are taking precautions.
Understanding Nipah Virus: What You Need to Know
To stay safe, it helps to understand what Nipah virus is and why health experts are concerned about it.
What Is Nipah Virus?
Nipah virus (NiV) is a deadly illness that spreads from animals to humans. Scientists call this a “zoonotic virus.”
The virus was first identified in 1999 in Malaysia during an outbreak among pig farmers. Since then, it has caused outbreaks almost every year in some parts of Asia, especially Bangladesh and India.
Where Does It Come From?
The natural hosts of Nipah virus are fruit bats, also called flying foxes. These bats carry the virus but don’t usually get sick from it.
The virus can spread to:
- Pigs (who can then spread it to humans)
- Other animals
- Humans directly from bats
Why Is It So Dangerous?
Nipah virus is considered one of the world’s most dangerous viruses for several reasons:
High death rate: Between 40% and 75% of infected people die. This is much higher than most other viruses.
No vaccine: Unlike diseases such as measles or COVID-19, we don’t have a vaccine to prevent Nipah virus.
No specific treatment: There’s no medicine that specifically kills the virus. Doctors can only treat the symptoms and help the body fight the infection.
Can spread person-to-person: Unlike some animal viruses that only spread from animals to humans, Nipah can spread between people.
WHO Priority Pathogen
The World Health Organization (WHO) lists Nipah as a priority pathogen. This means:
- It has high epidemic potential (could cause widespread outbreaks)
- It has a high fatality rate
- Research and preparedness are urgently needed
Symptoms to Watch For
Nipah virus symptoms appear 4 to 14 days after exposure. This is called the incubation period.
Early symptoms (similar to flu):
- Fever
- Headache
- Cough
- Sore throat
- Vomiting
- Muscle pain
Severe symptoms (in serious cases):
- Encephalitis (brain swelling)
- Confusion
- Seizures
- Difficulty breathing
- Pneumonia
- Coma
The virus attacks the brain and respiratory system. When it causes brain inflammation (encephalitis), it can be fatal.
Long-Term Effects
Even people who survive Nipah virus can face ongoing problems:
- Seizures
- Personality changes
- Behavioral changes
- Possible relapses (the virus can come back)
Some people can carry the virus without showing symptoms, which makes containment harder.
How Nipah Virus Spreads
Understanding how Nipah virus spreads helps you know how to protect yourself.
From Animals to Humans
The main way humans get Nipah virus is through contact with infected animals:
Direct contact with infected bats or pigs:
- Touching sick animals
- Cleaning areas where infected bats have been
- Working on farms with infected pigs
Consuming contaminated food or drinks:
- Eating fruit that bats have bitten or contaminated
- Drinking raw date palm sap (bats drink the sap and contaminate it)
- Eating unwashed produce
In Bangladesh, many Nipah cases have been linked to drinking raw date palm sap that fruit bats contaminated.
From Person to Person
Once someone is infected, they can spread the virus to others through:
Close contact with bodily fluids:
- Blood
- Saliva
- Urine
- Respiratory secretions
Respiratory droplets:
- Coughing
- Sneezing
- Talking at close range
This is why healthcare workers are at high risk. In the current West Bengal outbreak, five healthcare workers were the first cases detected.
Who Is Most at Risk?
Certain groups face higher risk of exposure:
Healthcare workers: Doctors, nurses, and hospital staff treating infected patients
Family members: People living with or caring for sick relatives
Farmers: Those working with pigs or in areas where fruit bats live
People in endemic areas: Residents of regions where Nipah appears regularly
Those who consume raw products: People drinking raw date palm sap or eating unwashed fruit
Airborne Transmission
Scientists know that Nipah virus can spread through respiratory droplets. In enclosed spaces with poor ventilation, airborne transmission is possible.
This is why healthcare workers must wear protective equipment, including masks, when treating patients.

Prevention and Protection Tips
Whether you’re traveling or just want to stay informed, here are important prevention measures.
How to Diagnose Nipah Virus
Early diagnosis is crucial for treatment and preventing spread.
Early-stage testing:
- RT-PCR tests (similar to COVID tests)
- Samples from throat swabs, nasal swabs, cerebrospinal fluid, urine, or blood
- These tests detect the virus’s genetic material
Later-stage testing:
- ELISA tests for antibodies
- These show if your immune system has responded to the virus
If you think you’ve been exposed, seek testing immediately. Don’t wait for symptoms to become severe.
Treatment Options
Currently, no specific antiviral treatment exists for Nipah virus. Treatment is supportive, meaning doctors help your body fight the infection:
Basic care:
- Plenty of fluids to prevent dehydration
- Rest
- Fever-reducing medications
Symptom management:
- Anti-nausea medicines
- Seizure medications if needed
- Breathing support for respiratory problems
Experimental treatments:
- Monoclonal antibody treatments are being studied
- These are special laboratory-made proteins that can fight the virus
- Supply is very limited and these are still experimental
Because there’s no cure, prevention is extremely important.
