Still, not all authorities agree that the symptoms caused by the so-called “novel” A(H1N1) virus are worse than those from seasonal flu.</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://healthspectator.com/2009/07/23/swine-flu-virulence-still-at-issue/"><P>Kawaoka’s lab used a version of the novel A(H1N1) virus referred to as CA04 because it originated from a patient diagnosed with H1N1 swine flu in California on April 9 of this year. Kawaoka states that “CA04 causes more severe lung lesions in non-human primates than does a contemporary human influenza virus” and further, that “in all three mammalian models tested, CA04 seemed to be more pathogenic than a contemporary human H1N1 virus, KUTK-4.”</P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://healthspectator.com/2009/07/23/swine-flu-virulence-still-at-issue/">Certainly the worst fear of all concerned is that the H1N1 virus could mutate into something resembling one of the current strains of avian flu such as H5N1, which has killed 50-60% of the humans it infected.</blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/383F1CCB-864C-42F4-BE16-ED8235005B71/blog/" title="blog or email this clip"><img src="http://content8.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
