Key takeaways

France reported the world's first human death due to the Shamonda virus in 2026.
The virus is spread by Culicoides midges and primarily affects livestock like cattle and sheep.
There are currently no specific vaccines or antiviral treatments available for this pathogen.
The WHO considers the public risk low as the fatality occurred in an immunocompromised individual.

France has recorded the world's first human death caused by the Shamonda virus. This is a major event because the virus previously only affected livestock. The World Health Organization (WHO) is now investigating the matter.

The Shamonda virus is a vector-borne virus. It belongs to the genus Orthobunyavirus within the Peribunyaviridae family and is part of the Simbu serogroup.
Scientists first found this virus in cattle in Nigeria in 1965. For a long time, it stayed in parts of Africa and Asia. However, it appeared in Europe, including Germany and France, in 2026.

The virus mainly attacks livestock such as cattle, sheep, goats, and horses. It has also been found in alpacas.
The virus spreads through the bites of infected Culicoides midges, which are very small flies.

There is no proof that the virus spreads from one human to another. Also, there is no record of the virus moving directly from animals to humans.
In livestock, the virus can move from an infected mother to her offspring. This is called vertical transmission.
In animals, the virus causes fever and lowers milk production. It also leads to serious reproductive disorders, such as stillbirths, spontaneous abortions, and congenital deformities in newborn animals.

Currently, there are no specific vaccines or antiviral medicines to treat this virus.
To manage the disease, people must focus on vector-control measures. This includes using insect repellents and destroying the places where midges breed.

The WHO believes the risk to the general public is still low.
Experts think this specific human death was a rare event. It happened because the patient had a very weak immune system, or was immunocompromised.
