Figure 5. Global and Iceland-specific reassortment patterns and Bayes factors among Hemagglutinin (HA) subtypes (5a and b), Multiple Correspondence Analysis of Host order and HA subtype (5c), and reassortment patterns and Bayes factors among Neuraminidase (NA) subtypes (5d and e). a) The global reassortment matrix of HA subtypes demonstrates the breadth and highly significant transitions between donor H1 subtypes and almost all other recipient subtypes. b) In Iceland, a strong association between donor H16 subtypes and recipient H2 subtypes were found, as well as other significant transitions between H3 and H10 and H11 subtypes and H2 and H10 subtypes. Both forward and reverse rates are visualized in these matrices, with subtypes labeled on the x-axis representing recipients and subtypes labeled on the y-axis representing donors. Bayes factors, signifying the level of significance, are represented as colors from beige (low) to dark red (high). c) Multiple correspondence analysis (MCA) of HA subtype by is presented host order. Size of blue rectangles for HA subtype corresponds to prevalence in the dataset. d) Global and e) Iceland-specific reassortment patterns and Bayes factors (BF) among Neuraminidase (NA) subtypes. The global reassortment matrix demonstrates the breadth and highly significant transitions between donor N8 subtypes and almost all other recipient subtypes. In Iceland, a strong association between donor N3 subtypes and recipient N7 subtypes were found, as well as other significant transitions between N8 and N9 and N7 subtypes. Both forward and reverse rates are visualized in these matrices, with subtypes labeled on the x-axis representing recipients and subtypes labeled on the y-axis representing donors. Bayes factors, signifying the level of significance, are represented as colors from white (low) to dark green (high).
