Between 28 June and 17 September 2018, 27 cases of human West Nile virus infections were recorded in Austria; four cases of West Nile neuroinvasive disease, 11 cases of West Nile fever, six infections detected by blood donation screening and six imported cases. In addition, 18 cases of human Usutu virus infections (all blood donors) were recorded. This is the highest number of annual infections recorded in Austria since the introduction of both viruses.

Eligibility Requirements

Abstract Context.—Informed consent in transfusion medicine has been an area lacking of significant research and it is unknown if donors fully comprehend the risks associated with whole blood donation. Objective.—To assess the adequacy of the informed consent process in whole blood donation. Design.—A brief questionnaire was constructed and distributed to whole blood donors visiting various fixed and mobile donor sites of the Central Pennsylvania Blood Bank. Questions consisted of demographic information; donor opinions of information content, length, and comprehension; and a short quiz pertaining to donor risks and eligibility. Results.—Analysis of 849 surveys demonstrated that donors comprehended a mean of 73.5% of the various donor eligibility and risks that were surveyed. Female and younger donors scored statistically higher on comprehension questions compared with male and older counterparts. Donors were most aware of (1) donor eligibility requirements related to acquired immunodeficiency syndrome comprehension, (2) the risk of dizziness postdonation, and (3) having lived in a certain country (93.7%–95.6% comprehension, respectively). Donors were least aware of (1) the risk of a possible referral to a physician for outstanding medical conditions or positive test results, (2) the risk of a positive test result, and (3) West Nile virus testing information (22.4%–49.3% comprehension, respectively). Conclusions.—Whole blood donors believed that they were giving informed consent, but a significant percentage of donors were unaware of several of the risks associated with blood donation, including participation in West Nile virus research testing. Our data suggest that donors do not fully comprehend the risks of whole blood donation and that repetition of information to the donor, and in multiple formats, strengthens the level of comprehension and thus the informed consent process.

Lineage 2

West Nile virus (WNV) lineage 2 is expanding and causing large outbreaks in Europe. In this study, we analyzed the epidemiological, clinical, and virological features of WNV lineage 2 infection during the large outbreak that occurred in northern Italy in 2018. The study population included 86 patients with neuroinvasive disease (WNND), 307 with fever (WNF), and 34 blood donors. Phylogenetic analysis of WNV full genome sequences from patients’ samples showed that the virus belonged to the widespread central/southern European clade of WNV lineage 2 and was circulating in the area at least since 2014. The incidence of WNND and WNF progressively increased with age and was higher in males than in females. Among WNND patients, the case fatality rate was 22%. About 70% of blood donors reported symptoms during follow-up. Within the first week after symptom onset, WNV RNA was detectable in the blood or urine of 80% of patients, while 20% and 40% of WNND and WNF patients, respectively, were WNV IgM-seronegative. In CSF samples of WNND patients, WNV RNA was typically detectable when WNV IgM antibodies were absent. Blunted or no WNV IgM response and high WNV IgG levels were observed in seven patients with previous flavivirus immunity.
