Overview
- The Friedrich‑Loeffler‑Institut analysed four samples and identified a previously uncharacterised Orthobunyavirus in the Simbu serogroup that it describes as “Shamonda‑like.”
- Regional authorities say about 100 cattle farms in Südbaden have reported cases, with adult animals showing mild signs such as fever, diarrhea and reduced milk yield and no reported deaths.
- The virus is transmitted by Culicoides biting midges and officials warn that midge activity through November could allow further and possibly rapid spread to more herds.
- Vets and researchers are investigating whether the virus crosses the placenta because related Simbu viruses can cause abortions, stillbirths and congenital defects, and no vaccine is currently available.
- Health agencies say there is no evidence so far of human infection, and experts note the finding echoes the 2011 arrival of Schmallenberg in Europe, which underscores uncertainty over economic and animal‑health impacts if the virus spreads.
