We tested blood samples from domestic and captive farmed animals in Minnesota, USA, to determine exposure to severe fever with thrombocytopenia syndrome virus and Heartland-like virus. We found antibodies against virus nucleoproteins in 10%-18% of samples from cattle, sheep, goats, deer, and elk in 24 Minnesota counties.
