Concurrent severe fever with thrombocytopenia syndrome virus outbreaks on multiple fox farms, China, 2023.

ABSTRACT: The role of farmed animals in the viral spillover from wild animals to humans is of growing importance. Between July and September of 2023 infectious disease outbreaks were reported on six Arctic fox (Vulpes lagopus) farms in Shandong and Liaoning provinces, China, which lasted for 2-3 months and resulted in tens to hundreds of fatalities per farm.
