Introduction

In the 30 days covering 2013-02-28 to 2013-03-29, the&nbsp;<span style="color: #783f04;"><b>United States CDC</b></span>&nbsp;released a total of 43&nbsp;<b><span style="color: #632423; font-family: &quot;Trebuchet MS&quot;;">pH1N1</span></b>&nbsp;sequences at&nbsp;<strong>GISAID&nbsp;</strong>on 41 human cases<strong>&nbsp;</strong>sampled from October 2012 to February 2013. Geographic surveillance includes&nbsp;<b>America,</b>&nbsp;<b>Africa, Asia </b>and<b> Russia.&nbsp;</b>Although&nbsp;<b><span style="color: #632423; font-family: &quot;Trebuchet MS&quot;;">pH1N1</span></b>&nbsp;in most locales during the&nbsp;2012-2013 season was the <b><span style="color: #783f04;">minority</span></b> serotype, the sequences in this Analytic Report describe a high level of human-infective diversity and an ease of avian genetic acquisition, including multiple instances demonstrating concentrated transport of <b><span style="color: #660000;">High-CFR</span></b>&nbsp;<b><span style="color: #632423; font-family: &quot;Trebuchet MS&quot;;">pH1N1&nbsp;</span><span style="color: #783f04;">Upsilon</span></b> polymorphisms onto single sequences.
