Shamonda virus

Have you heard of the Shamonda virus (SHAV)? If you live in Africa or Japan, you might know of it, but it has not been seen elsewhere until this past summer. It was found in German and Swiss cattle herds on July 31, 2026. While disease spread beyond a normal endemic area is not unusual, particularly due to climate change, surprising news related to SHAV occurred in France this fall.

On October 22, 2026, the first documented human SHAV infection was reported. Before then, SHAV only circulated in cattle, and other plant-eating, hoofed animals like sheep, goats, and horses. Spread by the bite of infected midges (known as gnats in the US), it can be a serious illness in herds. Unfortunately, on that October day, it killed the infected human.

As unfortunate as that was for that patient, it should not cause panic because that individual was severely immunocompromised, and individuals who are severely immunocompromised cannot fight off infections as well as those without that chronic condition. Instead, awareness, monitoring, and studying SHAV closely are prudent steps to discover how SHAV’s mutation affects humans.
