AI viruses are labeled by a combination of two groups of proteins: hemagglutinin or “H” proteins, of which there are 16 (H1–H16), and neuraminidase or “N” proteins, of which there are 9 (N1–N9). Lots of unique combos of “H” and “N” proteins are doable. Just about every mix is regarded as a distinctive subtype and can be further more broken down into diverse strains which flow into inside of flyways/geographic locations. AI viruses are further more classified by their pathogenicity (small or superior)—the means of a individual virus pressure to create disorder in domestic poultry.
