From Lisa Schnirring at CIDRAP, excerpt :
" Oct 8, 2010 : In its review of summer flu activity in the United States and across the globe today, the US Centers for Disease Control and Prevention (CDC) said that patterns, which included a few clusters and sporadic illness, were typical.
The CDC's report, however, which appears in today's issue of Morbidity and Mortality Weekly Report (MMWR), describes H3N2 influenza activity both globally and domestically, a strain often linked to more severe flu.
The report comes during the first official week of the US flu season.
Of respiratory samples from the United States that were analyzed over the summer, 326 (1.3%) were positive for influenza, of which 261 were influenza A and 65% were influenza B. Of the 185 influenza A viruses that were subtyped, most (70%) were H3N2, with rest the 2009 H1N1 subtype."
