Cutaneous coronavirus disease 2019 in children: a clinical primer for diagnosis and treatment.

PURPOSE OF REVIEW

This review examines the global literature regarding rashes encountered in children and adults infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and aims to provide practicing pediatricians with an understanding of the relationship between instances of rashes and coronavirus disease 2019 (COVID-19) in children in order to effectively evaluate and treat patients.

RECENT FINDINGS

The true incidence of cutaneous reactions in children infected with SARS-CoV-2 is not known. Children's immune systems differ from those of adults and rashes as a manifestation of immune responses, in turn, differ in morphology and distribution. Rarely, children develop a severe multisystem inflammatory syndrome that has overlapping clinical features with Kawasaki disease. In addition, vaccinations produce rashes similar to natural infections. The rashes associated with COVID-19 vaccination are mild and transient, and should not preclude vaccination. Lastly, children who chronically wear masks are more likely to experience flaring of acne around the nose and mouth ('maskne') and facial conditions such as seborrheic dermatitis.

SUMMARY

There are ongoing worldwide registries, clinical and basic science studies to better understand the burden of skin disease and pathophysiology of rashes seen in patients infected with COVID-19. Robust vaccination programs should be encouraged as a way to contain viral spread among children and the greater population.
