Then in March 2012 news appeared that a novel influenza A virus (H17N10) was circulating in fruit bats from Guatemala (Central America). Now, in October 2013, another new influenza A virus was identified from Peruvian bats. The genes that encode the surface proteins of the new virus from the flat-faced fruit bat were designated as new subtype H18N11. Officialy it is now named A/bat/Peru/10.

This all means that we now know of 18 different types of hemagglutinin (H) and 11 different types of neuraminidase (N) and it indicates that a total of 198 different subtypes of the Influenza A virus might exist.
