Transfusion-transmitted diseases other than AIDS and hepatitis.

Although the major diseases transmitted by transfusion today are AIDS and hepatitis, many others also are known. These include CMV, syphilis, Chagas disease, babesiosis, parvovirus B19, malaria, Epstein-Barr infection, and many others that have been reported only once or twice. Reducing the risk of transfusion-transmitted diseases is a problem for donor centers where donor screening and laboratory testing for possible carriers is undertaken. Physicians should be aware that the potential for disease transmission is always present when transfusions are administered.
