French authorities have announced the detection of the first known human case of the Shamonda virus (Shav) following the death of a patient in early October. Health officials described the incident as an exceptional case involving a severely immunocompromised individual, while reassuring the public that there is currently no risk to the wider community.
Shav is primarily known as a disease affecting cattle, sheep, goats, alpacas, and horses, spread mainly through infected midges, with human infections previously unheard of. The European Centre for Disease Prevention and Control (ECDC) stated it is monitoring the situation closely while officials continue to investigate how the virus transmission occurred.

The French health and agriculture ministries stated on Thursday that the patient is believed to have contracted the virus via a midge bite in eastern France, where animal cases were first identified during the spring. The patient was undergoing treatment for a serious illness at a hospital in Lyon and experienced neurological complications assessed as very likely linked to the virus based on preliminary findings.
The official statement emphasized that the patient's immune system was weakened, increasing vulnerability to illness. Dairy herds contracting the virus typically suffer from fever, diarrhea, and reduced milk production. The ECDC indicated it is working alongside French and European partners to evaluate potential public health implications.
The agency added that the first European cases of the virus were identified in late July, after which it appeared in farm animals across several regions including Ireland, Germany, Italy, Spain, and Jersey. The case has also been formally reported to the World Health Organization.
The detection of the Shamonda virus in a human highlights ongoing concerns regarding zoonotic spillovers and the crossover of animal pathogens into human populations. Although the patient's compromised immune system played a critical role, health authorities remain vigilant about monitoring vector-borne diseases amid shifting environmental conditions.
