Shamonda virus infects human for first time, causing death in France
The World Health Organization (WHO) is monitoring the first confirmed case of Shamonda virus infection in a human. The patient, an elderly man in eastern France with a severely weakened immune system, developed neurological symptoms including confusion and seizures in late September. He was diagnosed with severe encephalitis on September 25 and died on October 8, 2026.
While laboratory tests confirmed the presence of the Shamonda virus, authorities are still investigating the exact role the infection played in his death. The virus, which was first identified in cattle in Nigeria in 1965, has recently spread among various animal species across Europe, including Germany, Belgium, and the Netherlands.
Researchers suspect the virus may be transmitted via bites from Culicoides insects, which is how it spreads among animals, but human transmission via this method has not been documented. Currently, there is no evidence of human-to-human transmission, and French health authorities state there is no immediate risk to the general population. There are currently no specific vaccines or antiviral treatments available for the virus.
