Abbreviations cCMV Congenital Cytomegalovirus infection Dear Editor, We read with interest the article by Fernandez et al. [1], in which the authors describe an eightfold decrease (from 0.67 to 0.078%) in the prevalence of congenital Cytomegalovirus infection (cCMV) in Portugal during the COVID-19 pandemic. We would like to share the preliminary results of an ongoing universal screening study of cCMV in Hospital Sant Joan de Déu (Barcelona, Spain). The study was approved by the local Ethics Committee (ref. PIC-205-19); informed consent from parents is obtained at inclusion. cCMV screening is performed in saliva samples, obtained using flocked swabs (catalog no. 300267, Deltalab; Rubí, Spain) in the first 14 days of life, by means of the Alethia CMV DNA amplification assay (Meridian Bioscience; Cincinnati, OH) [2]; confirmation of cCMV is performed Communicated by Peter de Winter Antoni Noguera-Julian and Ana Alarcón contributed equally to this work.
