The Institute of Epidemiology, Disease Control and Research (IEDCR) reported that Nipah virus infections have been identified in 35 of Bangladesh’s 64 districts. The highest numbers of patients were found in Faridpur, Rajbari, Naogaon, and Lalmonirhat. The information was shared on January 7, 2026, during a meeting at the IEDCR auditorium on the spread and risks of the Nipah virus, chaired by Director Tahmina Shirin. The institute confirmed that five people died from the virus in 2024 and four in 2025.

IEDCR scientific officer Sharmin Sultana noted that Nipah cases usually occur from December to April, but infections were also detected in August 2025, suggesting possible new sources of transmission beyond raw date palm sap. For the first time, a case was recorded in Bhola district last year. She added that no effective treatment or vaccine exists yet, complicating the situation further.

Associate scientist Dr. Syed Moinuddin Sattar said surveillance has been strengthened in high-risk districts, and hospitals have been instructed to remain prepared. Experts advised avoiding raw date palm sap and unwashed or partially eaten fruits to prevent infection.
