Since mid-June 2026, an acute, non-fatal syndrome with high herd morbidity, reduced milk yield, diarrhea, fever and lethargy affected dairy cattle in southern Germany and Switzerland. Major viral pathogens were excluded. Pan-Simbuvirus PCR first detected an orthobunyavirus, subsequently confirmed by metagenomic sequencing, which enabled recovery of a complete “Shamonda-like” genome.
One sentence summary line
