France Reports First Human Death Linked to Shamonda Virus
France’s health and agriculture ministries said the patient was treated in Lyon and had severe immune suppression. The report, dated October 23rd 2026, identified the death as the first recorded human fatality associated with Shamonda virus. The authorities sent formal notification to the World Health Organisation and the European Centre for Disease Prevention and Control.
Shamonda virus belongs to the Orthobunyavirus family and had previously been known in veterinary settings since the 1960s, when it circulated among herds in Africa and Asia. It had historically been regarded as unable to infect people. During the recent spring and summer, however, the virus entered Europe and was reported on livestock farms in 14 western European countries. In France, infections were detected in 52 departments.
The principal route into ruminant populations is the bite of blood-feeding midges of the Culicoides genus. Cattle are the main hosts, while occasional detections have also been recorded in sheep and horses in areas with high vector density. In dairy herds, infection has been associated with short-lived fever, general discomfort, reduced feed intake and temporary declines in milk output.
French authorities said there was no technical evidence that the virus is transmitted through meat, pasteurised liquid milk or processed dairy products. European Union health rules require fluids from animals showing clinical signs of illness to be excluded from milk tanks and processing lines. The measures also apply before milk reaches refrigerated storage, which is maintained at 4°C, or industrial packaging facilities.
Public-health agencies said the risk to the general population remained very low because person-to-person transmission had not been identified. Dairy farms facing infected vectors have introduced additional measures including authorised insecticides, insect screens, topical repellents and the removal of standing water where midge larvae can develop. These steps add to operating costs for intensive and semi-intensive farms already exposed to changing prices for protein concentrates, silage and electricity.
Community agencies are providing molecular testing and entomological trapping without direct charges to producers, while temporary production losses affect farm revenues. Livestock organisations and dairy co-operatives have called for clearer guidance on managing herds in affected areas and for technical support for agricultural workers exposed to vectors. They have also requested continued surveillance of animal movements and genetic material, alongside stricter hygiene and veterinary monitoring in milking facilities.
