First Nipa Virus Death Reported in Bangladesh

Bangladesh has reported its first death due to the Nipa virus, the World Health Organization (WHO) has confirmed. According to the agency, the risk of international spread remains limited, but national health authorities have heightened vigilance in response to the case.

WHO stated on Friday, 6 February, that the patient, a woman aged between 40 and 50 from Naogaon district in the Rajshahi Division, was admitted to hospital in January 2026. Shortly after admission, she exhibited neurological symptoms, and laboratory tests on 22 January confirmed Nipa virus infection.

The WHO further noted that on 3 February, Bangladesh’s International Health Regulations National Focal Point (IHR NFP) formally notified the organisation about the case. The patient had no recent history of international travel, but she had consumed raw date palm sap, a known source of Nipa virus transmission.

Following the diagnosis, health authorities conducted tests on 35 individuals who had close contact with the patient. None were found to be infected, although authorities advised all contacts to maintain vigilance and follow preventive measures.

This incident has also drawn attention to recent Nipa outbreaks in the neighbouring Indian state of West Bengal, which have highlighted the importance of robust surveillance. Despite the seriousness of the virus, WHO has stated that no travel or trade restrictions are currently necessary.

WHO Director-General Dr Tedros Adhanom Ghebreyesus described the Nipa virus as a “rare but severe disease,” emphasising that enhanced monitoring, testing, and public awareness are key to preventing further spread. According to WHO assessments, the public health risk at national, regional, and global levels remains low.

The Bangladeshi government and health authorities continue to strengthen nationwide preparedness, with public education and adherence to proper hygiene regarded as the primary means of protection.

As the outbreak unfolds, authorities continue to emphasise public health measures, including awareness campaigns, personal hygiene, and prompt reporting of symptoms, to prevent further cases.
