Abstract

Abstract A woman with mild coronavirus disease 2019 developed cervical adenopathy, being diagnosed of Epstein-Barr virus infectious mononucleosis. We performed fine needle aspiration, and demonstrate that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is found in lymph nodes even in mild disease along with a strong expansion of terminally differentiated effector memory CD4+ T cells, a cell population that is practically absent in lymph nodes.
