First Human Case of Shamonda Virus Detected in France
French health authorities have confirmed the first human case of Shamonda virus, a livestock pathogen that had circulated quietly across Africa and Asia for decades without ever being detected in a person. The patient, a severely immunocompromised individual, died in early October 2026. The case was announced on October 22, 2026, and is considered an exceptional case involving a severely immunocompromised patient who was hospitalized for a serious medical condition, according to RTE.Investigation and Response
The investigation into the case is ongoing, with French authorities working to determine the transmission route and the virus's role in the patient's death. The patient was treated at Hospices Civils de Lyon in Lyon, France, and experienced neurological complications thought to have been "very likely linked" to the virus, according to RTE. The European Centre for Disease Prevention and Control (ECDC) is also evaluating the situation, as reported by Shattered.Shamonda Virus and Its Impact
Shamonda virus is an insect-borne virus that mainly affects cattle and other farm animals, and is spread by tiny biting insects called midges. The virus was first identified in Nigeria in the mid-1960s and has since been detected in animals in Africa, Asia, and Europe. The virus has been detected in 14 western European countries, according to an epidemiological bulletin from France's national research institute monitoring animal health.| Detail | Information |

| First detection in Europe | End of July 2026, including on cattle farms in France |
| Number of European countries affected | 14 western European countries |
| Main symptoms in cattle | Acute diarrhoea, fever, lethargy, and a drop in milk production |
Public Health Implications
The case has significant implications for public health, particularly for immunocompromised individuals. French health authorities have stated that there is no health risk to the general public identified at this time, but the investigation is ongoing, according to RTE. The ECDC is also monitoring the situation and providing guidance to other European countries, as reported by Shattered.Frequently Asked Questions
Is Shamonda virus contagious between humans?
There is no documented evidence of human-to-human transmission for Shamonda virus or any other Simbu serogroup virus, according to Shattered.
What is the Simbu serogroup, and are other viruses in it dangerous to humans?
The Simbu serogroup is a family of insect-borne orthobunyaviruses that mostly affect livestock. Oropouche virus, a relative, is a well-established human pathogen in South America, as reported by Shattered.
What happens next in the investigation?
French authorities say clinical, laboratory, and epidemiological work is continuing to pin down the transmission route and the virus's role, if any, in the patient's death, according to Shattered.
