3.2 Clinical manifestations
Clinical examination revealed that SFTS patients developed fever, gastrointestinal symptoms, and neurological symptoms, which mostly included fever, headache, dizziness, body aches, nausea, vomiting, and fatigue. Among the symptoms, fever (17/17), muscle pain (17/17), and headache (16/17) were the most frequent symptoms of SFTS. Clinical manifestations in confirmed and suspected SFTS cases were similar, showing that clinical manifestations alone cannot be used for diagnosis of SFTS (Table 1).
