在工业化国家中,由于敏感的HIV筛选试验的运用,供者延期献血制度的建立,以及使用血液更为谨慎等因素,极大地减少了输血途径传播HIV感染的发生。最近,在美国的血液经过HIV抗体筛选后阴性者其传播HIV的风险估计为1/440,000～660,000。尽管风险很低,公众对此持续的担扰对血液采集机构和保险部门形成的压力迫使他们去研究更为敏感的HIV筛选试验。基因组放大技术开始引起人们的注意并在德国进行了小规
In industrialized countries, HIV infection has been greatly reduced by transfusion routes due to the use of sensitive HIV screening tests, the establishment of donor delayed blood donation and the more cautious use of blood. Recently, the risk of HIV transmission in the United States negative for HIV antibody screening was estimated at 1 in 440,000 to 660,000. Despite the low risk, continued public pressure for this pressure on blood collection agencies and the insurance industry forces them to study more sensitive HIV screening tests. Genome amplification technology has begun to attract attention and made a small rule in Germany
