Influenza in Ireland Week 2 of 2012

January 20, 2012

Influenza activity in Ireland continued to increase during week 2 2012, however, remained at low levels. The sentinel GP influenza-like illness (ILI) consultation rate was slightly increased from the rate of week 1 2011. ILI rates remain below the Irish baseline threshold. To date this season, influenza A (H3) has been the dominant influenza virus detected. There were three confirmed influenza hospitalised cases notified during week 2 2012. One influenza B associated death was reported during week 2 2012, this is the first influenza-associated death reported for the 2011/2012 influenza season. One influenza A outbreak was reported in a hospital setting during week 2 2012. Influenza activity in the temperate regions of the northern hemisphere remained below seasonal threshold levels, although persistence of increased activity over recent weeks in some areas is likely to represent the start of influenza transmission. http://www.who.int/influenza/surveillance_monitoring/updates
