Abstract :
Infections remain one of the most serious problems in patients undergoing stem cell transplantation. With the progress concerning transplant techniques and the supportive treatment we observe decrease in the incidence of infectious complications early after transplant with extended duration and risks later. Viral infections constitute the specific group of complications, strictly related to the immunological reconstitution after the transplantation. Most often appearing infections caused by viruses of Herpesviridae family together with currently binding recommendations concerning the diagnostics, the prevention and the treatment are discussed in the paper.
