Reassortment is when two or more influenza virus strains infect a single host and then swap segments of their genetic material with each other. The more birds get infected with the H5N1 or N5N9 ...

Different blends of those two proteins alongside many other mutations elsewhere in the virus can affect how sick people and animals get and how it spreads. H5N1 has been the dominant grouping of ...

The combination of these proteins defines the virus subtype, such as H5N1 or H5N9. There are nine known subtypes of A(H5) viruses - A(H5N1), A(H5N2), A(H5N3), A(H5N4), A(H5N5), A(H5N6), A(H5N7), A ...
