WHO - Pandemic (H1N1) 2009 - update 94

WHO's latest update, please note Malaysia is still listed:

" The most active areas of pandemic influenza virus transmission currently are in parts of the tropical zones of Asia, the Americas, and Africa. Pandemic influenza activity remains low in much of the temperate areas of both the northern and southern hemispheres. Although pandemic influenza virus continues to be the predominant influenza virus circulating worldwide, seasonal influenza type B viruses are predominant in much of East Asia, and have been increasingly detected at low levels across southeast and western Asia, East Africa, and in parts of eastern and northern Europe. Seasonal influenza A (H3N2) is still being detected in very small numbers in parts of Asia and Australia.

In Southeast Asia, pandemic influenza virus transmission remains active but variable across the region. Thailand continues to report the most active circulation of pandemic virus in the region, however, disease activity may have recently peaked and begun to decline. Approximately half of all provinces in Thailand reported that >10% outpatient visits were due to influenza like illness (ILI). The proportion of outpatient sentinel respiratory samples testing positive for influenza dropped to 10% after peaking at approximately 30% during mid February 2010. In Malaysia, limited data suggest pandemic influenza virus transmission persists as new cases continue to be reported. In Indonesia, no recent pandemic influenza activity has been reported, however, low levels of seasonal influenza H3N2 and type B viruses continue to be detected. In Myanmar, limited data suggest that pandemic influenza has declined substantially since a period of active transmission during February 2010. "
