Introduction
In the 32 days covering 2013-10-17 to 2013-11-19, the <span style="color: #783f04;"><b>United States CDC</b></span> released a total of 49 <b><span style="color: #632423; font-family: "Trebuchet MS";">pH1N1</span></b> sequences at <strong>GISAID </strong>on 46 human cases<strong> </strong>sampled from February 2013 to October 2013. Geographic surveillance includes <b>America,</b> <b>Africa, Asia, Brazil, Ecuador, Paraguay </b>and<b> Peru. </b>
The sequences in this Analytic Report describe a high level of genetic activity at the <b><span style="color: #274e13;">Hemagglutinin</span></b> <b><span style="color: #660000;">antigenic area</span></b> between <b><span style="color: blue;">aa155</span></b> and <b><span style="color: blue;">aa158</span></b> with <b>5</b> amino variations and <b>4</b> silent revisions. <b><span style="color: #274e13;">HA</span></b> <b><span style="color: blue;">225G</span></b> is present in <b><span style="color: #660000;">quasi-species</span></b> on <b>2</b> American samples and as dominant form in <b>2</b> tropical countries. The <b>Dominican Republic</b> <b><span style="color: #274e13;">HA</span></b> <b><span style="color: blue;">225G</span></b> <b><span style="color: #660000;">Low Reactor Correlate</span></b> appears on a <b><span style="color: #7f6000;">TamiFlu Resistant</span></b> strain. <b><span style="color: #7f6000;">Drug Resistance</span></b> is also found in <b>2</b> US sequences and <b>1</b> South American case . . .
