COVID-19 induced immunosuppression leading to secondary infection in a non-HIV patient

Lymphopenia and immune dysfunction in COVID-19 is increasingly recognized and studied. This case report details a secondary infection following lymphopenia with CD4+ count drop in a COVID-19 patient with no history of immunosuppression or infection with HIV. The mechanism of lymphopenia, both CD4+ and CD8+ T cell count drops, in COVID-19 needs further study.
