    This report provides an update to the international flu situation using data collected through July 25, 2010, and reported by the World Health Organization (WHO) on July 30.

    Global Flu Activity Update: WHO continues to report laboratory-confirmed 2009 H1N1 flu deathsExternal Web Site IconExternal Web Site Icon on its Web page. These fatal cases are an under-representation of the actual numbers, as many deaths are never tested or recognized as flu related.

    Overall, flu activity due to 2009 H1N1 and seasonal flu viruses is low worldwide. However, some tropical regions, such as areas of the Americas and South and Southeast Asia, continue to report high levels of flu activity related to seasonal flu or 2009 H1N1. In the Northern Hemisphere, flu activity has been low or sporadic.

    Southern Hemisphere: In the Southern Hemisphere, levels of flu activity vary by location. There is low, but increasing, flu activity in Australia and New Zealand. In Australia, 2009 H1N1 is the most common virus strain, followed by influenza A (H3N2) viruses. Virologic data from South Africa suggests flu activity has peaked, but remains elevated, mostly due to seasonal influenza B and A (H3N2) viruses. Overall, levels of influenza-like illness (ILI) in Chile remain low, except in the Los Lagos region. The majority of flu viruses in Chile and Argentina are 2009 H1N1 and seasonal B viruses. In tropical regions of the Americas, 2009 H1N1 and seasonal flu virus activity was reported in early July.

    Asia: In Asia, India reported the most 2009 H1N1 activity. Low levels of 2009 H1N1 activity were also detected in several Southeast Asia countries, including Cambodia, Singapore and Malaysia. Singapore continues to report high levels of seasonal A (H3N2) activity.

    Africa: In Sub-Saharan Africa, seasonal A (H3N2) and B viruses continue to circulate in parts of Kenya and central Africa (Cameroon), and pandemic flu transmission continues in Ghana.
