FRANCE REPORTS FIRST HUMAN SHAMONDA VIRUS CASE, SAYS NO HEALTH RISK

France Reports First Human Shamonda Virus Case, Says No Public Health Risk Identified

France has reported the first documented human infection with Shamonda virus, a virus usually found in livestock. Health authorities say no risk to the general population has been identified at this stage.

The announcement came on Thursday, October 22, after the virus was detected in a patient who had been receiving treatment for a serious illness at a hospital in Lyon.

The patient, whose immune system was severely weakened, died in early October. Investigations are continuing to establish how the infection occurred and whether the virus caused or contributed to the death.

French officials described the case as exceptional. Although Shamonda virus has circulated among animals for decades, no human infection had previously been documented.

Investigators suspect the patient may have contracted it through the bite of a tiny insect known as a biting midge in eastern France. The virus had been circulating among animals in that region during spring and summer 2026. This possible route of infection has not yet been confirmed.

Shamonda virus mainly affects livestock, particularly cattle. It was first identified in Nigeria in the mid-1960s and was detected on European cattle farms, including in France, during summer 2026.

Authorities are continuing medical and scientific investigations. Their current assessment is that this unusual case does not indicate a wider public health threat, though the findings remain under review.
