France Reports First Human Shamonda Virus Case After Patient’s Death

French health authorities have reported the first known human case of the Shamonda virus after an infected patient died, raising concerns about the disease’s potential to affect humans.

However, authorities say there is currently no identified risk to the general population, according to reports published on Thursday, October 22, 2026.

The Shamonda virus primarily affects livestock, particularly cattle, and is transmitted by biting midges. It belongs to a group of viruses known as orthobunyaviruses.

The reported case marks a new development in disease monitoring, as French authorities had previously considered the virus incapable of infecting humans.

Authorities suspect the patient contracted the infection in eastern France, where the virus had been detected among animals during the spring and summer of 2026. However, the exact circumstances surrounding the infection and the route of transmission have not been fully established.

First identified in Nigeria in the 1960s, the Shamonda virus has since been detected sporadically in animals in parts of Africa and Japan. In 2026, it was also reported in livestock in several European countries.

The reported human infection has drawn renewed attention to the need for continued monitoring of emerging diseases and their potential impact on both animal and human health.

Veterinary authorities are continuing to monitor the virus among livestock as investigations into the reported case proceed.
