Overview
- Health authorities and regional labs have confirmed detections of the Shamonda-like orthobunyavirus across several German states and neighbouring countries in early September 2026, with cases now reported in cattle, sheep, goats, horses and alpacas.
- Affected animals typically develop fever, diarrhoea and a marked drop in milk production and most recover in days to weeks while many farms report persistent loss of yield during the lactation.
- Laboratory testing has found the virus in cattle fetuses on some farms, raising concern about possible abortions and congenital defects because the virus is related to the Schmallenberg virus.
- There is no vaccine and control relies on reducing midge exposure through repellents, stall insecticide use, improved ventilation and isolating suspect animals, according to the Friedrich-Loeffler-Institut and state labs.
- Surveillance is incomplete because the disease is not currently notifiable, leaving case counts uncertain and prompting calls from vets and farmer groups for wider testing and clearer guidance to limit economic and welfare impacts.
