Shamonda virus, USA News (Lyon, France): A severely immunocompromised patient receiving care at the Hospices Civils de Lyon died at the beginning of October 2026 following encephalitis linked to the Shamonda-Europe virus (SHAV-EU1). Medical authorities noted that this represents the very first time a human infection by this virus has been documented.
Traditionally transmitted by Culicoides midges among ruminants, the virus was detected in cattle farms across 52 French departments and several European nations over the summer. Public health officials emphasized that there is no established risk for the general population at this current stage.
