WHO Reports First Human Case of Shamonda Virus Disease, Citing Unknown Public Health Risk
The World Health Organization (WHO) reported the first known human case of Shamonda virus disease on October 20, 2026, releasing a situation report on November 2. Previously, Shamonda virus was considered a disease affecting only animals such as cattle, sheep, horses, alpacas, and goats, transmitted by biting midges. The individual in the reported human case was described as older and immunocompromised, with no recent travel history, suggesting local infection. The WHO has stated that the public health risk cannot yet be reliably assessed and recommends continued 'One Health Surveillance and investigation.' This indicates that the risk of exposure is currently unknown, and further research is needed before definitive recommendations can be made, though the risk of exposure is likely very low. Shamonda virus is closely related to the Schmallenberg virus, which also affects the same animals and is transmitted by midges, but has never been reported in humans.
