The SARS-CoV-2 pandemic raised many challenges for all patients with chronic conditions and those with autoimmune diseases, both adults and children. Autoimmune diseases are characterized by hyperreactivity of the immune system and loss of immune tolerance, which damage and destroy healthy tissues, cells, and organs.
