Since 2005, there are a number triple-reassortant swine flu (variant) viruses (H1N1v, H1N2v and H3N2v) circulating in the United States that created a number of serious infections in humans. So far they have failed to spread efficiently or to produce substantial levels of morbidity. To date 348 cases were reported to the CDC. See the table here.
 In November of 2011, substantial numbers of seals died in New England (USA). It was ultimately discovered that the cause was a new mammalian adapted influenza virus: H3N8 avian flu strain, versions of which are known to also infect horses and dogs. This Influenza A virus subtype, H3N8, appears to have a low risk of transmission to humans. News here.
 In March of 2012, a new Influenza A subtype was discovered in fruit bats: H17. That was a surprise because up to that moment it was thought that 16 different HA antigens (H1 to H16) and nine different NA antigens (N1 to N9) for influenza A were known. Birds are the natural host for influenza viruses but they had never been isolated in mammals before. New discoveries create new possibilities of infection and reassortment. News here.
 H6N1 is normally circulating in ducks. In May 2013 a 20-year old female was admitted to a hospital in Taiwan. After conducting whole genome sequencing, the National Influenza Center (NIC) at Taiwan CDC identified the virus to be a novel avian-origin influenza A (H6N1) virus. The patient recovered. See here.
