...than the U.S. has - and evolved to become less dangerous by the time it crossed the border. That would not be an unusual evolutionary device, since viruses that are too deadly cannot survive if they kill off their host before being given a chance to spread. "It's fairly common in epidemics to see a trade-off between the ability to cause severe death and transmissibility," says Steven Kleiboeker, a virologist and the chief scientific officer for ViraCor Laboratories. The A/H1N1 virus may be attenuating itself as it spreads from person to person, becoming easier to catch but less dangerous...

Birds are the natural reservoirs of the common flu strains that strike in winter - and those strains reassort themselves to hit humans particularly hard. But while humans are not susceptible to every strain of avian flu, pigs definitely are. When bird flu viruses replicate in pigs, they pick up the viral machinery that gives more selective flu strains the power to spread to other mammals, like us. That's what makes pigs such potent mixing bowls for flu. The roundabout bird-pig-human route may be less common than the straight bird-human jump, but it may be more problematic...
...strain which has contributed to its high degree of contagiousness among humans. The flu’s symptoms are similar to the standard influenza virus—including sore throat, fever, coughing, body aches, and chills. While Harvard students may not be wearing face masks—a common practice in several international cities—school health officials are clear about how to prevent an outbreak on campus. “I think the idea here is to be vigilant. The most important thing is to practice good hygiene” said David S. Rosenthal...
...Complaints about the Core and the nascent General Education—its lack of common requirements or a coherent, unifying philosophy—are rehearsed often. And the demise of a potential Great Books track within Gen Ed called further attention to this problem. The prevalence of grade inflation and the existence of trendy but “soft” disciplines in the humanities and social sciences continue to portend trouble to those concerned with Harvard’s intellectual rigor...
