• Description:
  This report provides an update to the international situation as of November 6, 2009. The World Health Organization (WHO) continues to report laboratory-confirmed 2009 H1N1 flu cases and deathsExternal Web Site Icon on its Web page. These laboratory-confirmed cases represent a substantial underestimation of total cases in the world, as many 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. Since April 19, 2009, more than 60% of all influenza positive specimens reported to WHO have been 2009 H1N1. In temperate regions of the Southern Hemisphere, disease due to 2009 H1N1 has returned to below baseline. In tropical regions of the Americas and Asia, influenza activity due to 2009 H1N1 remains variable. In temperate regions of the Northern Hemisphere, influenza-like illness (ILI) activity due to 2009 H1N1 continues to increase across many countries in Europe and Asia, as well as parts of the United States, Mexico and Canada.
