UNOS/OPTN has issued a bulletin covering Guidance for Organ Donation and Transplantation Professionals Regarding the Zika Virus. The bulletin includes notes about transfusion. Much information remains unknown, and the Guidance revolves around recent donor travel history and risk considerations, with the warning that vulnerability to Zika may also mean vulnerability to Dengue and Chikungunya. For details see https://optn.transplant.hrsa.gov/news/guidance-for-organ-donation-and-transplantation-professionals-regarding-the-zika-virus/ .
CDC has also issued a HAN Health Alert on Zika, HAN #392, CDC Recommendations for Subsequent Zika IgM Antibody Testing. It warns healthcare facilities that they may need to collect a second blood sample if they don’t hold back and refrigerate a portion of the original sample for additional testing.
