Preventing transfusion-transmitted infections: issues related to migrating populations and increasing world travel.
Blood donations by emigrants or other travelers from distant lands require special attention for the prevention of transfusion-transmitted infections. The human immunodeficiency virus, type 1 (HIV-1) is only one of several bloodborne viruses that may be introduced into non-epidemic areas by transfusion and spread further by sexual intercourse, needles shared by drug users or mother-child transmission. Although transfusion-transmitted parasites, such as Trypanosoma cruzi, do not spread further in non-endemic areas in the absence of specific vectors, such unlikely infections may cause serious disease before a diagnosis is made. The challenges posed by transfusion-transmitted infections in a shrinking world require specific preventive strategies and enhanced clinical awareness for timely diagnosis and treatment.
