The death toll due to encephalitishas climbed to 24 in Bangladesh. Nipah virus has been confirmed as the agent of disease by serologic test, and the cause of 4 more deaths Friday and Saturday in Rangpur and Lalmonirhat. The epidemic is currently confined to two villages, and control measures that include district-wide school closures are working to prevent spread. Latest victims are not constrained to a similar age class, ages 4, 16, and 42, suggesting that the Nipah virus is not a selective killer, and its lethality does not depend on a compromised immune system. Twenty-four new patients suffering encephalitis have been admitted to three regional health complexes and are undergoing treatment, with three in critical care.
