Laboratory findings for SFTS cases.

White blood cells (A), platelets (B), aspartate aminotransferase concentration (C), and lactate dehydrogenase concentration (D) in nonfatal and fatal cases at the time of admission and during hospitalization. Laboratory data are shown as the median and interquartile range between the first and third quartiles. Solid lines indicate nonfatal cases and dotted lines indicate fatal cases. The numbers of nonfatal and fatal cases are indicated for each onset day below the graph. The normal ranges for each parameter are 3,500–9,000/μL for WBC count, 15–35 × 10^4/μL for platelet count, 10–35 IU/L for AST, and 120–220 IU/L for serum LDH. * p < 0.05 between nonfatal and fatal cases.
