Nelson and her colleagues found that flu in pigs «follows long - distance swine movements from the southern U.S. to the Midwest,» with most of the human - origin H1N1 arriving at Midwest hog farms
coming from the Southeast, and most of the swine - origin H1N2
coming from the south - central U.S. And that means the Midwest, as the final
destination for many of these pigs, is «likely to provide a reservoir for
multiple genetically distinct variants to co-circulate and exchange segments via re-assortment because of the continual importation of swine influenza viruses from other regions,» the researchers noted.
Other surfaces, such as bounce pads, don't count as reload locations, so if you're
coming up to an area that features
multiple bounce pads leading to your
destination, be sure to save those two shots for when you really need them.
