however remained low in all age groups.  Influenza positivity increased during week 5 2014, with 64 (23.5%) influenza positive specimens reported
from the National Virus Reference Laboratory (NVRL): 31 influenza A(H3), 27 influenza A(H1)pdm09 and 6
influenza A (not subtyped).  Respiratory syncytial virus (RSV) positivity decreased significantly during week 5 2014, with 20 (8.1%) RSV
positive specimens reported from the NVRL.  Sporadic detections of adenovirus, human metapneumovirus and parainfluenza viruses have been
reported from the NVRL for the 2013/2014 season to date.  Fifteen confirmed influenza A hospitalised cases were reported to HPSC during week 5 2014, bringing the
total number of hospitalised cases reported this season to 56.  Sixteen confirmed influenza cases were admitted to ICU and reported to HPSC to date this season, seven

Increase in influenza-like illness

During week 9 2014 (week ending March 2nd), the general practitioner consultation rate for influenza-like illness (ILI) in Ireland increased to 53.6 per 100,000 population from an updated rate of 50.5 per 100,000 during week 8 (week ending February 23rd). This rate exceeds the Irish baseline threshold of 21 per 100,000 for the fifth consecutive week (used to assess influenza activity during the 2013/2014 influenza season in Ireland). The rate of increase during week 9 was most pronounced in the 5-14 year age group. Influenza A(H3) is the predominant virus in circulation with influenza A(H1)pdm09 co-circulating. The flu report for week 9 is available here.

Due to the levels of influenza activity reported last week in Ireland, antiviral drugs for the treatment and/or prevention of influenza in at-risk patients are recommended in line with the Interim guidelines on the use of antivirals for the treatment and prophylaxis of influenza which are available here.
