Acute polyarthritis associated with hantavirus infection

Abstract

Haemorrhagic fever with renal syndrome (HFRS) is the most common clinical manifestation of hantavirus infection. The major clinical findings are fever, headache, lumbar pain, and abdominal pain. However, a wide variety of additional symptoms can also occur since multiple organ systems are involved in HFRS, for example, the kidneys, the gastrointestinal tract, the respiratory tract, and the central nervous system [1,2]. But acute polyarthritis as a clinical manifestation of HFRS has not been previously reported.

We report the case of a 63-year-old Korean man who developed fever, chills, pharyngitis, and acute polyarthalgia with renal failure. To our knowledge, this is the first report of acute polyarthritis in HFRS.
