Shamonda virus detected in a human for the first time
France has recorded the first documented human case of Shamonda virus worldwide.
The patient, who was severely immunocompromised, died in early October while being treated for a serious illness at a hospital in Lyon.
The virus had previously been found in cattle in France and Europe in summer 2026, after cows developed fever and diarrhoea.
It was considered unable to infect people, and the patient’s infection is a first for humans.
Authorities suspect the patient was infected by a biting midge in eastern France, where the virus was already circulating.
They say no risk to the general population has been identified based on current knowledge.
Investigations into the case are continuing, and French authorities have notified the World Health Organization and the European Centre for Disease Prevention and Control.
