amid an unsettling report these days of tamiflu resistance in a very danish a(h1n1) affected person, comes a study during the new england journal of medication tracing the swine flu's 90-year evolution.
the current flu strain has genetic roots in an sickness that sickened pigs at a swine exhibit in 1918 in cedar rapids, iowa. a near-century of improvement considering the fact that then can incorporate this flu's accidental resurrection from an extinct strain.
here's what possible went down. simultaneously the 1918 flu pandemic was spreading among humans, pigs had been hit with a identical respiratory illness. early experiments confirmed the 1918 swine virus including a human strain emerged with regards to the identical time.
as outlined by the authors of your new paper,
Microsoft Office 2007 Pro Plus Product Key, there was a momentary "extinction" of this strain of virus from humans in 1957. but then it reemerged 20 years later in a very small 230-person outbreak in 1976 among soldiers in fort dix,

however the next 12 months h1n1 reemerged in people in the soviet union, hong kong,
Microsoft Office 2010 Home And Business Key, and northeastern china. the genetic origin of that 1977 strain turns out not to be the 1976 fort dix strain. instead, it was closely related to a 1950 human strain.
which means that given the genetic similarity with the two strains, reemergence was likely due to an accidental release during laboratory studies with the 1950 strain that had been preserved as a "freezer" virus.
ouch. hate it when that happens.
the authors hypothesize that concerns about the fort dix outbreak stimulated a flurry of research on h1n1 viruses in 1976,

or maybe it wasn't such an accidental a release? conspiracists,
