The World Health Organization (WHO) confirmed a woman died in northern Bangladesh in January after contracting the deadly Nipah virus. The patient, aged between 40 and 50, showed symptoms starting January 21, including fever, headache, hypersalivation, disorientation, and convulsions. She died one week later. The infection was confirmed a day after her death. The woman had no travel history but consumed raw date palm sap, a known source of Nipah virus. WHO stated, "All 35 people who had contact with the patient are being monitored and have tested negative for the virus, and no further cases have been detected to date." Nipah virus spreads mainly through products contaminated by infected bats, like fruit. It can be fatal in up to 75% of cases but does not spread easily between people. Following recent Nipah cases in India, countries such as Malaysia, Thailand, Indonesia, and Pakistan have increased airport temperature screenings. WHO said, "The risk of international disease spread is considered low and that it does not recommend any travel or trade restrictions based on current information." In 2025, Bangladesh reported four laboratory-confirmed fatal Nipah cases. There are currently no licensed medicines or vaccines for Nipah virus infection.
