About Novel and Variant Influenza A Viruses
Novel and Varient 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 avian influenza A (H5N1, H7N3, and now H7N9), and variant influenza A (H3N2v and H1N2v) viruses have been reported. At this time, no cases of human infection with avian influenza A H7N9 viruses have been detected in the United States.
