Small Epidemic Outbreak of Norovirus in the Pediatric Department of Brescia Civic Hospital (Northern Italy): Genomic Characterization and Phylogenetic Analysis

Our analysis confirmed a nosocomial outbreak and underscored the substantial intra-genotypic diversity of GII.4 Sydney 2012 [P16] genotype. These findings highlight the importance of rapid diagnosis, infection control measures and continuous genomic surveillance to track the evolution and global circulation of epidemic noroviruses.
