Autologous hematopoietic stem cell transplantation (HSCT) for relapsed Hodgkin's lymphoma increases the risk of infection by using intensive chemotherapy. This risk is obviously ongoing given the increased virulence of severe COVID-19. We report a case of a young man with Hodgkin's lymphoma who received conditioning chemotherapy followed by autologous HSCT and tested positive for SARS-CoV-2 by polymerase chain reaction (PCR) during the early phase of aplasia with persistence of COVID-19 beyond 30 days with favorable follow-up and clinical improvement on treatment. For this type of patient with hematologic malignancy, viral infection can be fatal and strict medical precautions with isolation rules must be maintained, especially for SARS-CoV-2.
