Authorities in India are on high alert after five confirmed cases of the deadly Nipah virus were reported in West Bengal. The outbreak, centred around a private hospital near Kolkata, has prompted neighboring Asian countries to implement strict health checks for travelers arriving from India to prevent any cross-border transmission.
Which countries have tightened airport rules?
Following the reports from West Bengal, several Asian nations have intensified screening at their entry points. Travelers from India should expect delays and health checks upon arrival.
| Country | Action Taken |

| Thailand | Fever screening and health cards at Suvarnabhumi & Phuket airports for West Bengal arrivals. |
| Nepal | Intensified screening at Tribhuvan Airport and land borders with India. |
| Taiwan | Issued a Level 2 travel alert for visitors going to affected Indian regions. |
What is the situation in West Bengal?
The outbreak started in early January 2026. According to official data, five people have tested positive, primarily healthcare workers including doctors and nurses in the Barasat area. Authorities have quarantined nearly 200 contacts who are being closely monitored. Fortunately, no new cases have been reported as of late January.
What are the common symptoms?
The Nipah virus can cause severe respiratory and neurological complications. The incubation period ranges from 4 to 14 days.
- Mild Symptoms: Fever, headache, muscle pain, vomiting, and sore throat.
- Severe Symptoms: Dizziness, drowsiness, acute respiratory distress, and encephalitis (inflammation of the brain).
Is there a vaccine available?
Currently, there is no licensed cure or vaccine for the Nipah virus globally, and treatment relies on supportive care. However, medical science is moving forward. A new vaccine candidate, PHV02, is entering Phase II human trials in Bangladesh this year, showing promise for future prevention.
