Sentinel GP influenza-like illness consultations for the 2020/2021 season have been above the Irish baseline threshold (18.1/100,000 population) for five consecutive weeks but, to date, were reflecting SARS-CoV-2 activity, rather than influenza, according to the latest Health Protection Surveillance Centre (HPSC) influenza surveillance report. No confirmed influenza hospitalised or critical care cases had been notified to HPSC and there had been no reports of deaths up until December 20.
