Global flu activity rose in the first half of November, mainly due to rising levels in North America, parts of Europe, and a few locations in other regions, the World Health Organization said this week in a regular update.
The United States and Canada are experiencing earlier-than-expected flu surges at levels higher than in prepandemic years. Europe's activity is also rising, with many countries above their epidemic thresholds and Germany and Portugal reporting widespread activity.
Elsewhere, flu detections rose in parts of the Middle East, especially in Iran. And in temperate South America, flu activity remained elevated in Argentina and Chile.
Testing respiratory specimens at global flu labs reveals that influenza A made up 95.2% of samples during the first half of November. Of the subtyped influenza A viruses, 83.7% were H3N2. Of the characterized influenza B viruses, all belonged to the Victoria lineage.
