Low Seroprevalence of West Nile Virus in Blood Donors from Catalonia, Spain Piron, Maria Plasència, Antoni Fleta Soriano, Eva Martínez, Ana Martínez, J. P.

Trilla García, Antoni Pumarola Suñé, Tomàs Martínez Yoldi, Miguel Julián Donants de sang Malalties víriques Catalunya Blood donors Virus diseases Catalonia West Nile virus (WNV) is an emerging arbovirus first recognized in Europe in the 1950s. Since then, outbreaks have been reported in several European countries. In 2010, the first WNV outbreak was recorded in Spain, affecting the southern part of the country. We conducted a seroprevalence study in the Catalonia region (northeastern Spain), an area considered at high risk of arbovirus transmission. A total of 800 serum samples from blood donors were collected and screened for antibodies against WNV by enzyme-linked immunosorbent assay (ELISA) and confirmed by a microneutralization assay. More than 50 samples tested positive by ELISA, but only one sample contained neutralizing antibodies against WNV and was obtained from a donor native of Pakistan. The low seroprevalence detected may serve as reference baseline data for monitoring WNV activity in our region in future years. 2016-06-15T11:04:40Z 2016-12-18T23:01:11Z 2015-12-18 2016-06-13T15:59:48Z info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Versió postprint del document publicat a: http://dx.doi.org/10.1089/vbz.2015.1787 Vector Borne and Zoonotic Diseases, 2015, vol. 15, num. 12, p. 782-784 http://dx.doi.org/10.1089/vbz.2015.1787 (c) Mary Ann Liebert, 2015 info:eu-repo/semantics/openAccess Mary Ann Liebert Articles publicats en revistes (ISGlobal)
