acquired

Authorities believe the virus was acquired via an animal source; however, the teen was not on a farm nor near any known wild birds or backyard poultry — common reservoirs for the disease.

Nuzzo also pointed to a recent study published in Nature, led by Yoshihiro Kawaoka, an H5N1 expert at the University of Wisconsin, in Madison, that showed the virus that infected the first reported dairy worker in Texas had acquired mutations that made it more severe in animals as well as allowing it to move more efficiently between them — via airborne respiration.

Nuzzo said there are other hypotheses — which she stressed are just hypotheses — including one that posits people who were exposed to the H1N1 swine flu outbreak in 2009 may have acquired some immunity to the “N1” part of the virus.

He recently acquired an old house near his studio in Mar Vista just so he could strip its parts for new art pieces.

That year, it was acquired by the London-based Moonbug Entertainment, which also bought fellow YouTube children’s program “Blippi.”
