    This report provides an update to the international flu situation using data collected through March 21, 2010, and reported by the World Health Organization (WHO) on March 26. WHO continues to report laboratory-confirmed 2009 H1N1 flu cases and deaths on its Web page. 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.

    Overall, 2009 H1N1 activity is highest in certain areas of Southeast Asia, West Africa, and tropical regions of the Americas. An increase in 2009 H1N1 activity has been reported in recent weeks in Central America and the tropical regions of South America. In West Africa, limited data show that 2009 H1N1 activity continues and may not have peaked. Although the 2009 H1N1 virus continues to be the predominant influenza virus circulating worldwide, seasonal influenza B viruses predominate in East Asia, and are circulating at low levels across Southeast and Western Asia, Eastern Africa, and in parts of Europe. In the temperate areas of the Southern Hemisphere, 2009 H1N1 activity remains low.
