Figure 3. Signs and Symptoms of SARS-CoV-2 Infection.

The varied presentation of SARS-CoV-2 infection reflects diversity in host immune responses, notably in immunosuppressed transplant recipients. Studies of viral strains and receptors are in progress. Acral lesions, which are purpuric macules, papules, vesicles, or pustules, may be described as “Covid toes” or “pseudo-chilblains,” among other terms.⁷ ARDS denotes acute respiratory distress syndrome, and CNS central nervous system.
