...officials on April 16 of a possibly uncommon flu virus, one whose symptoms also include splitting headaches as well as the pneumonia-related problems. What Lezana seems to have conveniently left out is that Mexico as of then still did not have a proper laboratory to test for that viral strain; and that the WHO may not have been able to move with full force until a Canadian and then a U.S. lab confirmed the A/H1N1 variety eight days later...
...student, who was started on anti-viral medication when flu was first diagnosed early this week, was at home and doing well, Rosenthal said last night...
...virus genes. That could especially help with swine flu, since researchers found back in the 1970s that the virus doesn't grow well in chicken eggs; that could slash the yield and slow production of a potential new vaccine. "As long as we get the genetic sequence of some viral proteins, it doesn't matter where the virus came from - human, swine or bird," says Singhvi. So far, Novavax's shot is still in the testing phase, but its VLP-based vaccines against seasonal and bird flu are providing good results. The company stands ready to try its strategy against...
...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. Strains of avian...
...dead rose steadily - from 58 reported fatalities on Friday to 149 dead by the tally on Monday. The total number of people who have been hospitalized for the infection shot up to more than 2,000, although two-thirds of these had checked out after successfully responding to anti-viral drugs.
