Severe fever with thrombocytopenia syndrome (SFTS) is a tick-borne viral disease with a high mortality rate. Infection can also occur through close contact with an infected patient. Scrub typhus is an acute febrile illness caused by Orientia tsutsugamushi, a bacterium transmitted to humans through chigger mite bites. South Korea is an endemic region of SFTS and scrub typhus. In this study, we confirmed that a patient was coinfected with SFTS virus and two (Boryong and Taguchi) genotypes of O. tsutsugamushi.
