Summary
? Influenza activity in Ireland remained at low levels during week 9 2012. Several indicators are showing
that influenza activity may have reached its peak for the 2011/2012 season.**
? The sentinel GP influenza‐like illness (ILI) consultation rate was 34.6 per 100,000 population in week 9
2012, a slight decrease compared to the updated rate of 41.8 per 100,000 during week 8 2011.**
Š ILI rates remain above the Irish baseline threshold (25.9 per 100,000 population).**
Š The highest age specific ILI rates were in the 0‐4 year age group during week 9 2012.**
? Forty‐five influenza positive specimens were detected by the NVRL during week 9 2012. Influenza A (H3) has been the dominant influenza virus detected this season.
? The proportion of respiratory syncytial virus (RSV) positive detections increased slightly during week 9 2012. RSV activity peaked this season during week 52 2011.**
? Three adenovirus and four human metapneumovirus (hMPV) positive detections were reported during week 9 2012. Positivity levels for hMPV, adenovirus and parainfluenza viruses have remained low this season.***
? Seventeen confirmed influenza hospitalised cases were notified during week 9 2012.**
? One confirmed influenza A (H3) case was admitted to critical care and reported to HPSC during week 9
2012. To date this season, six influenza A (H3) cases admitted to critical care have been reported to HPSC.**
? Three influenza‐associated deaths have been reported to HPSC to date this season.***
? Two influenza A outbreaks were reported to HPSC during week 9 2012. To date this season, six influenza outbreaks and one RSV outbreak have been reported.
? In Europe, the 2011/2012 influenza season started later than in recent seasons and has been without any clear geographic progression. The national influenza season epidemics have peaked in the first affected
