About our Nipah Virus news
Latest news on Nipah Virus, covering outbreaks, symptoms, transmission, prevention, and developments in this emerging infectious disease threat.
Nipah Virus is a deadly zoonotic disease carried by fruit bats of the Pteropus genus, also known as flying foxes. First identified during an outbreak in Malaysia in 1998, the virus has since caused recurring outbreaks primarily in Bangladesh and India. With a case fatality rate ranging from 40 to 75 per cent, Nipah Virus is recognised by the World Health Organisation as a priority pathogen with pandemic potential.
Recent outbreaks demonstrate the ongoing threat posed by this disease. In 2025, Bangladesh reported four fatal cases, while India recorded four confirmed cases in Kerala with two deaths. In January 2026, authorities in West Bengal, India, placed around 100 people under quarantine following new suspected cases. The virus spreads through contaminated date palm sap, fruits partially eaten by infected bats, and direct human-to-human transmission through close contact with infected individuals. Symptoms include fever, headache, respiratory distress, and in severe cases, acute encephalitis that can lead to coma within 24 to 48 hours.
Efforts to combat Nipah Virus have intensified in recent years. In December 2025, the University of Oxford launched the world's first Phase II clinical trial of the ChAdOx1 NipahB vaccine in Bangladesh, enrolling 306 participants. The vaccine, built on the same platform as the Oxford-AstraZeneca vaccine, received PRIME designation from the European Medicines Agency in June 2025. The Serum Institute of India is manufacturing up to 100,000 investigational doses that could be deployed during future outbreaks. However, no approved vaccine or specific treatment currently exists, and patient care relies on intensive supportive therapy.
Prevention remains crucial for communities living in outbreak-prone regions. Public health campaigns focus on avoiding raw date palm sap consumption, washing fruits thoroughly, and reducing bat access to food collection sites through protective coverings. Healthcare workers face particular risk during outbreaks, as nosocomial transmission has occurred in previous cases. Surveillance systems in Bangladesh and India have improved significantly, with early detection and contact tracing helping to contain outbreaks before they spread widely.
The virus has left a lasting impact since that first Malaysian outbreak, which affected 283 people and caused 109 deaths. Bangladesh has documented 347 cases through its surveillance system, with a case fatality rate of 71.7 per cent. Many survivors face long-term neurological complications, including memory loss, personality changes, and seizures. The seasonal pattern of outbreaks in Bangladesh, occurring between December and May during date palm sap harvesting, underscores the complex relationship between human agricultural practices, wildlife, and disease transmission.
