Molecular dating suggests that these reassortment events were completed in August 2016 and thus most likely occurred in wild birds in Russia-Mongolia.
Together, these findings illustrate that single reassortment events or mutations can lead to the emergence of transmissible variants of pandemic 2009 or seasonal A(H1N1) viruses unresponsive to most, if not all, of our currently available drugs.
The results don't mean that those viruses aren't exchanging genes, Perez says, as low levels of reassortment could go undetected.
The 1957 "Asian flu" pandemic, on the other hand, emerged as a result of reassortment.
The current pandemic influenza (H1N1) 2009 virus arose from a subsequent reassortment event from the triple reassortant swine influenza A (H1N1) virus.
They have the unique distinction of having segmented genome which permits them reassortment in their genetic structure resulting in evolution of new subtypes.
The types are susceptible to reassortment, each reassortment taking on different qualities.
Reassortment could result in a pandemic virus emerging, which has the potential to infect millions of people worldwide.
Helprin warns of the possibility of reassortment, whereby humans (or one of the few types of animals that can contract human flu) also contract avian flu, and the two merge to form a super-hybrid, with the worst aspects of both.
This reassortment could result in a combination virus that has the human flu's ability to spread and the bird flu's ability to kill.
The first is by a process called reassortment - when genetic material is exchanged between human and avian viruses during co-infection of a human.
It changes by genetic mutation or reassortment during viral replication.
