Novel and Variant Influenza A Viruses
Flu viruses constantly change and mutate. Novel and variant influenza A viruses can infect and cause severe respiratory illness in humans. These influenza viruses are different from currently circulating human influenza A virus subtypes and include influenza viruses from predominantly avian and swine origin.
In recent years, human infections with highly pathogenic influenza A (H5N1, H5N2, H7N3, and H7N9), and variant influenza A (H3N2v, H1N2v, and H1N1v) viruses have been reported.
- Novel Influenza A (H5N1, H5N2, H7N9)
New (novel) and highly pathogenic influenza A viruses have the potential to cause a pandemic if the virus were to change to become easily and sustainably spread from person-to-person. 2009 H1N1, (H1N1)pdm09, is no longer considered a novel strain.

- Variant Influenza A (H3N2v, H1N2v, H1N1v)
Variant influenza A viruses do not usually infect people and are very different from human seasonal viruses. Influenza viruses that normally circulate in pigs are called “variant” viruses when they are found in people.
