Lyon:French health authorities have reported the first documented human infection with the Shamonda virus, an emerging pathogen previously only known to affect livestock. The infection was identified in a patient with severe immunodeficiency who was undergoing treatment for a serious illness, leading to their death in early October.

According to Anadolu Agency – English, the clinical, biological, and epidemiological investigations are ongoing following the death. The Shamonda virus, part of the orthobunyavirus group, is primarily transmitted through bites from Culicoides midges. This virus, similar to Schmallenberg virus and Akabane virus, was first discovered in Nigeria in the 1960s and has since been sporadically reported in Africa, Japan, and more recently in Europe.

The French Health Ministry noted that the patient was treated at the Hospices Civils de Lyon hospital group. Before the patient's death, neurological complications were observed, which authorities believe were likely linked to the Shamonda infection. They suggest the patient may have contracted the virus via a midge bite in eastern France, where the virus was circulating among animals.

The virus has been known to cause symptoms such as fever, diarrhea, and reduced milk production in cattle, and can lead to reproductive issues during pregnancy. While the virus primarily affects cattle, it has also been found in small ruminants and horses in Europe. Despite the virus not being classified as a regulated animal disease in the EU, authorities recommend preventive measures to reduce midge exposure.

French authorities continue to investigate the virus's spread and have informed international health organizations, although no risk to the general population has been identified at this time.
