HPS Weekly National Influenza Report - week ending 31 December 2017

ERRATUM: Please note that the legend of the Figure 1 was incorrect and this has now been amended. 

In week 52, overall assessment is yellow (normal seas​on activity). Seasonal influenza is having a moderate impact on the population. There is continuing evidence of increasing secondary care pressure based on virological detections of influenza.

Community circulation of influenza prompted the issue of a CMO letter​ in week 50 advising that GPs may prescribe antivirals.
