France reports first human case of livestock virus Shamonda
Authorities say the infection appears isolated in a severely immunocompromised patient, and investigators are still examining how the virus spread.
On Oct 22, 2026, French health authorities confirmed the first human case of the Shamonda virus in a patient who later died, though officials see no risk to the general population at this stage.
Transmitted by biting midges, the Shamonda virus is an insect-borne Orthobunyavirus primarily affecting livestock, which The French government noted was previously considered non-transmissible to humans.
First identified in Nigeria in the 1960s, the virus has been detected sporadically in Africa and Japan, and has been spreading among several European countries throughout 2026.
Earlier this month, the Department of Agriculture detected the virus in cattle samples from two farms in Cork, stating this was the first time "this emergent virus has been detected in Ireland."
Infection likely occurred in eastern France, where authorities hypothesize the virus had been circulating among animals during spring and summer 2026.
