(University of Maryland) In the first study to examine how the H1N1 pandemic virus interacts with other flu strains, laboratory research by the University of Maryland found no evidence of "reassortment" to form a more virulent "superbug," but did demonstrate the heightened communicability of the pandemic form responsible for the so-called swine flu.
The pandemic virus prevailed over and out-competed the other strains in ferrets, reproducing, on average, twice as much.
