Inclusion criteria

Inclusion criteria: (1) Japanese male or female patients aged 20 or above at the time of obtaining informed consent (2) Patients in which SARS-CoV-2 was detected from the upper and lower respiratory tract specimens using polymerase chain reaction (PCR) or loop-mediated isothermal amplification, or those who were positive for the antigen at least 3 days before obtaining the informed consent. (3) Patients who have been provided with complete information about the contents of the informed consent form and other study-related details, and who voluntarily sign the informed consent form to participate in the study after having understood the study content.

Exclusion criteria
