We isolated a new orthonairovirus from Dermacentor silvarum ticks near the China-North Korea border. Phylogenetic analysis showed 71.9%-73.0% nucleic acid identity to the recently discovered Songling orthonairovirus, which causes febrile illness in humans. We recommend enhanced surveillance for infection by this new virus among humans and livestock.
