ALT = alanine aminotransferase; AST = aspartate aminotransferase; cELISA = Cellular enzyme-linked immunosorbent assayCK = creatine kinase; CK-MB = creatine kinase-MB; IFA = Immunofluorescence assay; LDH = lactate dehydrogenase; MNA = microneutralization assay; N/A = not applicable PLT = platelet count; WBC = white blood cells. + = positive; − = negative. Clinical parameters below the normal range are shown in bold numbers with down arrows; and those over the normal range are shown in bold with up arrows.

^*Virus was isolated from the serum sample of case B collected on July 30.

^†Listed are the blood counts on the first day of admission and the serum biochemistry on the last day of admission.

^‡The positive antibody titer was expressed as the reciprocal of the dilution at which the optical density value was three times higher than the negative controls.
