Thu, 05 Nov 2026 00:00:00 +0000 On 2 November 2026, World Health Organization (WHO) published an update following the first ever known case of Shamonda virus (SHAV) infection in a human. The case was an immunocompromised older man from eastern France with no travel history during the preceding year. He developed severe encephalitis (brain inflammation) and died in early October 2026. Vector-borne transmission (via a bite from an infected midge) is thought to be the most likely source of infection. Food-borne transmission is unlikely but remains under investigation. As this is the first documented laboratory confirmed human infection, WHO considers that the public health risk cannot yet be reliably assessed and recommends continued surveillance and investigation.
