Summary
Preventive measures have significantly reduced HIV transmission via blood products, but challenges remain in regions with high HIV prevalence and inadequate blood donation systems. Ongoing efforts focus on improved screening and donor selection to minimize residual risks.
Area of Science:
- Infectious Diseases
- Public Health
- Hematology
Background:
- Transfusion-transmitted HIV infection has been a recognized risk since 1982.
- Preventive strategies have substantially decreased HIV transmission associated with blood products.
- Global disparities exist in managing transfusion-related HIV risks due to varying healthcare infrastructures.
Purpose of the Study:
- To review the historical context and current status of HIV transmission risk in blood transfusions.
- To evaluate the effectiveness of implemented preventive measures.
- To highlight ongoing challenges and future directions for risk mitigation.
Main Methods:
- Review of historical data and scientific literature on transfusion-transmitted HIV.
- Analysis of the impact of screening tests and donor selection protocols.
- Discussion of public health strategies for donor education and deferral.
Main Results:
- Significant reduction in HIV transmission risk from blood components and plasma derivatives in many regions.
- Persistent challenges in areas with high HIV prevalence and reliance on replacement donors.
- Residual risk, though low in developed nations, necessitates continued vigilance.
Conclusions:
- Effective blood transfusion safety relies on robust screening and voluntary non-remunerated donation systems.
- Enhanced donor information and education are crucial for minimizing residual HIV transmission risks.
- Addressing global inequities in blood safety is essential for public health.
