A woman in northern Bangladesh has died after contracting the deadly Nipah virus in January, a case confirmed by The World Health Organisation. This incident follows an outbreak of Nipah virus cases identified in neighbouring India, which has already prompted the implementation of Covid-era border controls to prevent further spread.

The Nipah virus is a rare yet severe infectious disease primarily carried by bats. It poses a significant threat to human health, with UK health chiefs estimating a fatality rate of up to 75 percent among infected individuals. Beyond mortality, survivors can experience lasting neurological difficulties, including persistent seizures and personality changes, and in rare instances, the virus can lay dormant and reactivate months or even years after the initial infection.

The patient, a woman aged between 40 and 50, developed a fever and neurological symptoms consistent with Nipah virus on January 21. Her initial symptoms included headache, muscle cramps, loss of appetite, and vomiting. Her condition rapidly deteriorated, leading to confusion, hypersalivation, and convulsions. She became unconscious on January 27 and succumbed to the illness the following day after being admitted to hospital. Investigations revealed she had no travel history, but it was reported that she had repeatedly consumed raw date palm sap in the weeks leading up to her death, a common route of infection resulting from consuming fruits or sap contaminated with the faeces or saliva of infected fruit bats.

This case marks the first reported Nipah virus death outside of India since recent outbreaks, intensifying global pandemic concerns. Previously, two Nipah virus cases were confirmed in India's West Bengal State. In response to these developments, several Asian countries, including Malaysia, Thailand, Indonesia, and Pakistan, have implemented temperature screenings at airports as a precautionary measure to control the virus's spread.

The WHO has confirmed that all 35 individuals who had been in contact with the deceased patient are being closely monitored and have tested negative for the virus, with no further cases detected to date. WHO chief Tedros Ghebreyesus stated last week that authorities have increased disease surveillance and testing, implemented prevention and control measures in healthcare settings, and are actively informing the public on protective measures. The UK Health Security also issued new guidance, emphasizing the importance of understanding the virus for those planning travel to areas where it circulates, despite the overall risk remaining very low for most people.

Historically, Bangladesh has reported more than 340 Nipah virus cases since 2001, with approximately half of these linked to the consumption of raw palm sap. Officials continue to monitor the virus diligently, as there is currently no vaccine or specific treatment available for Nipah virus infection, making early detection and containment critical.
