Introduction
The COVID-19 pandemic caused by ‘Severe acute respiratory syndrome
coronavirus 2’ (SARS-CoV-2A) was first described at the end of 2019 and
have spread all over the world. Although elderly and people with
comorbidities are the most affected by the severe manifestations of the
disease, COVID-19 seems to affect children to a lesser
degree.1 Data concerning the impact of COVID-19 on
hematopoietic stem cell transplant (HSCT) patients are scarce and
variable. There are few reports – mostly from adults- regarding risk of
COVID-19-associated complications secondary to immunosuppressive therapy
or delayed immune reconstitution at the post-transplant
period.2 However, little is known about children and
adolescents with HSCT. Here, we report an adolescent patient who was
diagnosed with COVID-19 after hematopoietic stem cell transplantation
and had graft-versus-host disease (GVHD) triggered by COVID-19.
