X-Linked Agammaglobulinemia and COVID-19: Two Case Reports and Review of Literature.

The Centers for Disease Control and Prevention (CDC) has listed primary immunodeficiency disorders as being predisposed to severe coronavirus disease 2019 (COVID-19).

In this study, we present 2 boys in late adolescence from south India with XLA who were infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), as well as a review of cases reported in the literature.
