However, there have been less than 10 documented transfusion\u2010transmitted cases since World War II.

Universal donor screening was reported by 35 of 36 institutions providing policy data, with treponemal assays representing the predominant screening approach. Substantial variation was observed in confirmatory testing, donor deferral criteria and donor re\u2010entry policies. Reactivity rates varied markedly across centres and were higher among first\u2010time donors compared to repeat donors. Institutions with higher syphilis rates generally reported higher donor reactivity. Routine leukoreduction was reported by 66.7% of institutions, while pathogen reduction technologies were routinely used by 36.1%. Most centres apply indefinite donor deferral and have not considered removing screening.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Syphilis screening and donor management practices vary across blood services worldwide despite widespread implementation of universal screening.
