Our study revealed a higher incidence of this virus infection, more than double the values reported in studies previously published in the Americas (8-11), except for the serosurveys conducted in Guadeloupe and Martinique, which showed values similar to ours; however, only adults eligible for blood donation were included in the population of that study (9).…”
