Weekly influenza surveillance overview, week 1, 2014
For week 1/2014:
? Of the 29 reporting countries, 28 reported low-intensity influenza activity while Spain reported medium intensity.
? Of 305 sentinel specimens tested across 24 countries, 70 (23%) from 11 countries were positive for influenza virus.
? The viruses circulating this season remain well-matched with the 2013/14 seasonal vaccine viruses.
? Thirty-six hospitalised laboratory-confirmed influenza cases were reported by Ireland, Spain, Sweden and the UK.
Based on reports of widespread, local or sporadic spread from the majority of countries and the increasing proportion of specimens testing positive for influenza virus across 11 countries, which is indicative of influenza transmission, the season appears to be slowly getting started in EU/EEA countries.
Legend:
No report: Intensity level was not reported
Low: No influenza activity or influenza at baseline levels
Medium: Usual levels of influenza activity
High: Higher than usual levels of influenza activity
Very high: Particularly severe levels of influenza activity
+: Increasing clinical activity
-: Decreasing clinical activity
=: Stable clinical activity
Legend:
No report: Activity level was not reported
No activity: No evidence of influenza virus activity (clinical activity remains at baseline levels)
Sporadic: Isolated cases of laboratory confirmed influenza infection
Local outbreak: Increased influenza activity in local areas (e.g. a city) within a region, or outbreaks in two or more institutions (e.g. schools) within a region (laboratory confirmed)
Regional activity: Influenza activity above baseline levels in one or more regions with a population comprising less than 50% of the country's total population (laboratory confirmed)
Widespread: Influenza activity above baseline levels in one or more regions with a population comprising 50% or more of the country's population (laboratory confirmed)
