Hantavirus infection is seldom reported in Taiwan. The spectrum of clinical severity ranges from mild to severe and may cover Hantavirus pulmonary syndrome and hemorrhagic fever with renal syndrome (HFRS). We report a case of HFRS in a 24-year-old soldier presenting with fever, chills, abdominal pain and generalized myalgia. His clinical course progressed through febrile, hypotensive, oliguria and polyuria phases. Hantavirus infection was proven by serology at the second hospital week. The patient was successfully treated with supportive management. Clinicians should be alert to the possibility of HFRS when examining patients with symptoms of fever, renal function impairment, hemorrhagic tendency and with rural exposure in Taiwan.
