WHO says fatal case of Nipah virus confirmed in Bangladesh | World Health Organization News

The World Health Organization (WHO) has reported a fatality in Bangladesh linked to the Nipah virus, while simultaneously assessing the risk of international spread as low. This follows recent confirmed cases in neighboring India, prompting heightened vigilance across the region.

Recent Cases and Global Response

On February 3, 2026, Bangladesh’s International Health Regulations National Focal Point (IHR NFP) notified the WHO of a confirmed Nipah virus (NiV) infection in the Rajshahi Division. The patient, a woman between 40 and 50 years old from the Naogaon district, began experiencing fever and neurological symptoms on January 21. She had no reported travel history but had consumed raw date palm sap prior to becoming ill.

Did You Know? Approximately half of all reported Nipah virus cases in Bangladesh since 2001 have been linked to the consumption of raw date palm sap.

This case emerges roughly a week after two cases were confirmed in West Bengal state, India. Authorities in India are currently working to contain the virus, which they state remains largely under control. The outbreak in India has led to increased health screening at airports in China and several Southeast Asian nations.

Understanding the Nipah Virus

The WHO characterizes Nipah virus as a “rare but serious disease.” The organization emphasizes that, based on current information, it does not recommend any travel or trade restrictions. WHO Director-General Tedros Adhanom Ghebreyesus stated that authorities are actively increasing disease surveillance, implementing preventative measures in healthcare settings, and keeping the public informed.

Expert Insight: The WHO’s assessment of a low risk of international spread, despite confirmed cases in multiple countries, suggests a focused and effective containment strategy is currently in place. However, the high fatality rate associated with Nipah virus underscores the importance of continued vigilance and rapid response.

Currently, Notice no licensed medicines or vaccines specifically designed to combat Nipah virus infection. Reports indicate a high fatality rate, ranging from 40 to 75 percent, among those infected.

Potential Future Scenarios

If further cases emerge in Bangladesh, it is likely that health officials will expand contact tracing efforts. A possible next step could involve increased public health messaging regarding the risks associated with consuming raw date palm sap. Should cases continue to rise in India, neighboring countries may consider strengthening their own surveillance and screening protocols. It is also possible that research into potential treatments and vaccines could be accelerated.
