*ALT, alanine aminotransferase; AST, aspartate aminotransferase; SARS-CoV-2, severe acute respiratory syndrome coronavirus 2.
†Contact 2 had 4 serial negative throat swabs for SARS-CoV-2, and negative influenza A, influenza B, respiratory syncytial virus, parainfluenza virus, adenoviridae, Epistein-Barr virus, cucumber mosaic virus, mycoplasma, and chlamydia results. He had elevated AST and ALT and was negative for hepatitis A, B, C, and E; he had no jaundice or gastrointestinal symptoms. His AST and ALT returned to normal after 9 days of treatment with glycyrrhizinate 50 mg 3 times daily and vitamin C (0.2 g 3×/d).
‡Contact 3 had an elevated D-dimer level without anemia, bleeding, or evidence of a coagulopathy. She received vitamin C (0.2 g 3 ×/d). After the SARS-CoV-2 nucleic acid (throat swab) test was negative, her D-dimer level returned to normal (111 ng/mL).
