Nipah virus (NiV) is a highly contagious pathogen with an extremely high fatality rate, ranging from 40% to 75%. Although only isolated outbreaks have been reported to date, its potential for transmission and severe clinical outcomes have led the World Health Organization (WHO) to designate Nipah virus as a priority pathogen with epidemic potential. Currently, there are no specific vaccines or targeted treatments available, and many survivors suffer from severe, long-term neurological sequelae.
Epidemiological Situation (as of January 26, 2026):
- Global: India reported 5 suspected cases (including 2 confirmed cases) in West Bengal State between December 27, 2025, and January 26, 2026.
- Vietnam: No cases have been recorded to date.
What is Nipah Virus?
Nipah virus is a Group A pathogen that causes severe infectious disease, transmitted from animals to humans or through contaminated food and items.
It is not a novel virus; it was first identified in 1999 during an outbreak among pig farmers in Malaysia. In 2001, human cases of Nipah virus infection were first recorded in Bangladesh and subsequently in India, causing several severe recurring outbreaks.
How is Nipah Virus Transmitted?
- Direct contact with infected animals (such as bats or pigs).
- Consumption of food contaminated with secretions from infected animals.
- Human-to-human transmission through direct contact with an infected person’s bodily fluids and secretions.
Suspected Symptoms of Nipah Virus Infection
The incubation period typically ranges from 4 to 14 days. Stay vigilant if you experience the following symptoms:
- Sudden high fever, severe headache, and myalgia (muscle pain).
- Shortness of breath and respiratory distress.
- Severe disease progression: Dizziness, altered consciousness, acute encephalitis, which can rapidly progress to a coma within 24 to 48 hours.
Preventive Measures
- Avoid non-essential travel to regions experiencing active outbreaks.
- Monitor health post-travel: Within 14 days after returning from an affected area, if you develop symptoms such as headache, muscle pain, vomiting, sore throat, dizziness, drowsiness, confusion, or seizures, seek immediate medical attention at the nearest healthcare facility. Avoid close contact with others and fully disclose your travel and epidemiological history.
- Practice strict food hygiene: Ensure food is thoroughly cooked and water is boiled; wash and peel fruits before eating; discard fruits with signs of bat or bird bites/nibbles; avoid drinking fresh, unprocessed raw date palm sap or fruit juices.
- Avoid exposure to reservoir hosts: Do not come into close contact with fruit bats; wash hands frequently with soap and water or alcohol-based hand sanitizer after touching animals.
- Infection control in caregiving: Limit direct contact with suspected or confirmed patients; when providing care, wear personal protective equipment (PPE), including masks and gloves, and perform thorough hand hygiene after contact.
