A case of severe fever with thrombocytopenia syndrome caused by a novel bunyavirus in Zhejiang, China

Abstract

Two typical symptoms of severe fever with thrombocytopenia syndrome (SFTS) are fever and thrombocytopenia. Here we report a laboratory confirmed SFTS case with no fever during the entire hospitalization period, in Daishan County, Zhejiang Province, China. A 77-year-old woman was admitted to hospital with symptoms including nausea, retching, and anorexia. Laboratory tests revealed thrombocytopenia, leukopenia, and liver and brain damage. The case was later confirmed as a novel bunyavirus infection. Epidemiological investigations revealed that she had no history of tick bites or skin damage, and no known exposure to persons with a similar illness in the area prior to illness onset. The patient was hospitalized for 15 days, and during the whole admission period, she did not experience any fever. The patient recovered and was discharged.
