Summary
Preventing transfusion-transmitted infections involves careful donor selection and rigorous screening for parasitic, bacterial, and viral pathogens. Viral hepatitis remains the most frequent infectious risk, while human immunodeficiency virus (HIV) risk is minimized through screening.
Area of Science:
- Transfusion Medicine
- Infectious Disease Control
Background:
- Transfusion of blood products carries risks of parasitic, bacterial, and viral infections.
- Infectious agents can be transmitted via whole blood, packed red blood cells, platelets, fresh-frozen plasma, and cryoprecipitate.
Purpose of the Study:
- To outline the infectious risks associated with blood transfusions.
- To describe the key strategies for preventing transfusion-transmitted infections.
Main Methods:
- Review of established protocols for blood collection and storage.
- Analysis of donor selection criteria and laboratory screening procedures.
- Evaluation of current infectious disease surveillance in transfusion medicine.
Main Results:
- Viral hepatitis, particularly non-A, non-B hepatitis, is the leading infectious risk in US transfusions.
- Syphilis, hepatitis B, and human immunodeficiency virus (HIV) are routinely screened for in donor blood.
- Effective donor screening and self-deferral significantly reduce the risk of HIV transmission.
Conclusions:
- Comprehensive donor screening and meticulous collection/storage practices are crucial for transfusion safety.
- Ongoing vigilance is necessary to mitigate the risk of transfusion-transmitted infections, with viral hepatitis being a primary concern.
