Though influenza B activity has defined the season in some countries in North America, only 29.8% of recent samples worldwide were classified as influenza B. Flu activity remains high in North America, with H1N1 and B viruses circulating, the WHO said. Though influenza activity remains high across Europe, several northern European countries reported a decrease of detections, including Ireland, England, and Wales. Russia has reported a predominance of influenza B, as have several countries in central Asia. Flu activity remains elevated in most East Asia countries.
