These laboratory-confirmed cases represent a substantial underestimation of total cases in the world, as most countries focus surveillance and laboratory testing only on people with severe illness.
  
  The 2009 H1N1 influenza virus continues to be the dominant influenza virus in circulation in the world. For the most recent period in which data are available, from January 17, 2009 to January 23, 2010, 54% were typed as influenza A and 46% as influenza B. Out of all subtyped influenza A viruses, 93% were 2009 H1N1 positive.
  
  In temperate regions of the Southern Hemisphere, sporadic cases of 2009 H1N1 continue to be reported but no substantial increases in influenza activity have been observed. In the northern temperate and tropical regions of the Americas, 2009 H1N1 activity continues to decrease or remain low in most places. Influenza transmission continues to remain active in North Africa, certain areas of Eastern and Southeastern Europe, and parts of South and East Asia.
