SARS-CoV-2 Infection in an Adolescent With X-linked Agammaglobulinemia.

We present a case of a 17-year-old boy with X-linked agammaglobulinemia who had mild disease when initially infected with SARS-CoV-2 but after recovering from acute infection developed fevers and a raised erythrocyte sedimentation rate that persisted for several weeks without any ongoing respiratory symptoms. Multiple nasopharyngeal swabs were found to be negative for SARS-CoV-2 during the febrile period, but typical changes of COVID-19 on high resolution CT chest scan led to the detection of SARS-CoV-2 on RT-PCR in a sample from a bronchoalveolar lavage. His fevers completely resolved after a 5-day course of remdesivir.
