Abstract
Vitamin D is an important cornerstone in the immunologic cascade of many skin infections, systemic infections with cutaneous presentations, and other infectious dermatologic diseases where infections could be a culprit. Vitamin D supplementation is proposed as a protective measure against their occurrence and exacerbation, especially with the emergence of several viral pandemics in recent years. Vitamin D plays a key role in the maintenance of a balanced immunologic profile which could be reflected by a lowered incidence and morbidity of infections. Vitamin D screening and supplementation in patients with deficiencies or insufficiencies should be a part of the dermatologic approach to patients with these diseases.
