The World Health Organization’s Director-General, Tedros Adhanom Ghebreyesus, highlights that Nipah virus infections remain rare yet pose a significant health risk. Current outbreaks appear confined to India, with no reports other nations.
Recent Cases and Response Measures
Tedros noted in a recent social media update that India has confirmed two Nipah virus infections in West Bengal, marking the third such incident in the state since the virus’s initial detection in 1998. Health authorities continue to monitor over 190 individuals who may have been exposed, and no additional infections have emerged so far.
Efforts include enhanced disease surveillance, expanded testing, and robust prevention protocols in healthcare facilities. Public awareness campaigns also educate communities on protective steps against the virus.
This alert follows the WHO’s assessment that the current situation presents a low risk of wider spread, with no recommendations for travel or trade limitations. Evidence shows no increase in human-to-human transmission, maintaining the overall threat level as contained.
Details of West Bengal Outbreak
In North 24 Parganas district, two nurses tested positive for Nipah virus. Both exhibited severe symptoms starting in late December 2025 and received hospital care in early January 2026. By January 21, 2026, the male nurse showed full recovery and was discharged, while the female nurse continues observation after ventilator support ended, with signs of improvement.
Historical Context and India’s Preparedness
Nipah cases in India have stayed relatively low since 2001, except for notable surges of 66 infections in 2001 and 18 in 2018. Over the last five years, approximately a dozen confirmed cases occurred, all in Kerala. The nation maintains vigilant systems, including continuous monitoring, rapid response teams at central and state levels, and advanced laboratory diagnostics to address potential outbreaks swiftly.
Understanding Nipah Virus
Nipah virus spreads as a zoonotic pathogen, primarily from animals to humans, though contaminated food or direct person-to-person contact can also transmit it. Infected individuals often face fever accompanied by neurological issues like headaches or confusion, and respiratory problems such as coughing or breathing difficulties.
Discovered in 1998, the virus has appeared in Bangladesh, India, Malaysia, the Philippines, and Singapore. Its case fatality rate varies between 40% and 75%, underscoring the need for prompt intervention.
