The World Health Organization (WHO) confirmed a fatal case of Nipah virus in Bangladesh. The patient, a woman aged 40-50 from Naogaon district, died after falling ill on January 21. She had no travel history but recently drank raw date palm sap, a known infection source. The patient was admitted to hospital on January 28, and lab tests confirmed Nipah virus on January 29. WHO said 35 contacts were tested, with no new cases found yet. Since 2001, Bangladesh reported about 348 Nipah cases, half linked to raw palm sap. Cases appear seasonally from December to April during palm sap harvest. The virus has a high fatality rate of 40-75 percent. Recently, two Nipah cases appeared in West Bengal, India, raising regional concerns and tougher airport screenings in Southeast Asia and China. However, WHO states the risk of international spread remains low. WHO chief Tedros Adhanom Ghebreyesus called Nipah "a rare but serious disease" and praised increased surveillance, testing, and public awareness efforts by authorities. He said, "Authorities have increased disease surveillance and testing, implemented prevention and control measures in health care settings, and are keeping the public informed about how to protect themselves." There is currently no specific vaccine or treatment for Nipah virus, making containment vital.
