The World Health Organization (WHO) has confirmed the death of a woman from Naogaon district, Bangladesh, due to Nipah virus infection. The confirmation came through an official statement released on Friday. Following the detection of this new case in the Rajshahi division, authorities have increased surveillance in border areas. The patient, aged between 40 and 50, developed fever, headache, and breathing difficulties on January 21. Her condition worsened, leading to hospitalization on January 27. Laboratory tests on January 29 confirmed Nipah virus infection, and she later died while under treatment.

According to WHO, Bangladesh’s International Health Regulations National Focal Point informed the organization of the confirmed infection on February 3. Investigations found that the woman had no recent travel history but had consumed raw date palm sap before falling ill. The virus is primarily carried by fruit bats of the Pteropus species, which can contaminate sap with saliva or droppings during winter.

Since 2001, Bangladesh has recorded 348 Nipah virus cases, about half linked to drinking raw date palm sap, while others resulted from human-to-human transmission.
