Fig. 1

Phylogenetic analysis of NoV GII sequences (1 kb) detected in 20 healthcare workers (HCW) from outbreak wards B2, C1 and C2 (Table 1), spring 2012. Representative NoV GII.4 sequences from HCWs in ward B2, C1or C2 are shown in red as HCWidn (HCW identification number); The non-GII.4 strain, from HCW252, is included. Pidn (blue) represents GII.4 sequences reported previously from patients in the given ward. The number of identical sequences from the ward are outlined as (n)*. ENV (green) indicates NoV GII.4 sequences from environmental sites in the given ward: pt (patient table), wb (wash-hand basin), av (air vent), vt (virus trap)2 Relevant NoV GII.4 reference strains, with GenBank accession numbers, are included. The bar indicates genetic distance per nucleotide/site
