^{^a}

Normal range of circulating immune cell subsets: B cells, 90‐560/μL; helper T cells, 550‐1440/μL; suppressor/cytotoxic T cells, 320‐1250/μL.

^{^b}

Determination of plasma nucleic acid of SARS‐CoV‐2 in cases 3, 5, and 6 by One‐step RT‐ddPCR, SARS‐CoV‐2 infection as confirmed by the positive result of a throat swab test in cases 2 and 8. +, SARS‐CoV‐2 infection continued.

^{^c}

+, Case 2 is still in hospital.
