​For week 2/2014:
• Of the 30 reporting countries, four (Bulgaria, Greece, Portugal and Spain) reported medium intensity of influenza and Portugal, Spain and the UK (England) reported geographically widespread activity.
• Of 842 sentinel specimens tested across 25 countries, 217 (26%) from 16 countries were positive for influenza virus.
• Bulgaria, Greece, Spain and the UK (Scotland) reported influenza A(H1)pdm09 virus as the dominant subtype.
• Ireland, Romania, Spain, and Sweden reported 97 hospitalised laboratory-confirmed influenza cases.
Based on reports of geographically widespread ILI activity in three countries and the growing number of countries with an increasing proportion of specimens testing positive for influenza virus, which is an indicator of influenza transmission, the season has now started in EU/EEA countries.
