Shamonda virus (SHAV) is an orthobunyavirus of the Simbu serogroup and is closely related to Schmallenberg virus (SBV). It is believed to be spread by Culicoides biting midges, which also spread SBV and bluetongue virus.
During 2026, outbreaks of acute disease associated with SHAV were described in cattle in several European countries, including the Republic of Ireland, Jersey and Great Britain. Historically, SHAV had only been detected in Africa and Asia, making its occurrence in Europe unusual. Two genetically distinct variants or clades are known to be circulating in Europe, Shamonda virus European Clade I (SHAV-EU1) and Shamonda virus European Clade II (SHAV-EU2).
