Abstract

We report a human case of severe fever with thrombocytopenia syndrome virus infection transmitted by a tick, confirmed by viral identification. Haemaphysalis aborensis, a tick species not native to Japan that has been observed to transmit the virus to humans, is now recognized as a potential vector of this virus in Japan.

Keywords: Japan; febrile diseases; severe fever with thrombocytopenia syndrome; severe fever with thrombocytopenia syndrome virus; tickborne infections; ticks; vector-borne infections; viruses.
