France: First Human Shamonda Virus Case Confirmed

France has confirmed its first human case of the Shamonda virus, tragically resulting in the patient's death. This marks a significant development as the virus, primarily affecting livestock like cattle, sheep, and goats, has reached Europe for the first time this year. First detected in Nigeria in 1965, Shamonda virus had previously been confined to Africa and Asia.

The virus was identified in Europe in late July, and by October, over 20 cases were reported across more than a dozen countries, including major cattle-breeding nations like France, Germany, Spain, and Ireland. French authorities suspect the virus has been circulating domestically since the spring.

Symptoms in animals include fever, diarrhea, and reduced milk production, with more severe complications like abortions and fetal malformations reported. The World Organisation for Animal Health is still assessing the long-term impact of the European variants.

The human case involved a patient in Lyon with a severely compromised immune system. While the patient's brain complications are strongly suspected to be linked to Shamonda, investigations are ongoing. The UN's World Health Organization has stated that, based on current knowledge of related viruses, this is likely an isolated human event with a low probability of wider spread at this time. Infection is thought to have occurred via a midge bite in eastern France.
