The latest influenza update from the World Health Organization, excerpt :
Influenza activity is increasing on the European continent, particularly in the central, south and eastern part. In the tropics, several countries of southern Asia have seen a recent increase in influenza virus transmission mainly due to influenza A(H1N1) 2009 virus.
Other tropical areas of the world and the temperate countries of the southern hemisphere are currently reporting very little influenza circulation. Influenza transmission in North America, notably in the United States of America (USA) has increased this week with a slight increase of (H1N1) 2009 compared to earlier weeks.
Transmission in most of northern Africa and the Middle East has peaked recently and is declining. Some countries in northern Asia are seeing an increase in (H1N1) 2009 transmissions and some are seeing an increase in influenza-like illness activity.
The majority of the viruses characterized from North America and Europe are closely related to the vaccine viruses for the current seasonal vaccines."
