In week 1, the overall assessment is amber (moderate season 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 and increasing number of cases that have required ICU care. It is difficult to assess the contribution of influenza to the very high statistically significant excess in all cause mortality reported in weeks 52 and week 1 but ICU mortality due to laboratory confirmed influenza is low.
It’s not too late to be vaccinated - vaccination of those eligible for seasonal influenza remains the most important preventative measure to reduce influenza. An increase in community circulation of influenza that prompted the issue of a CMO letter in week 50 and the advice that GPs may prescribe antivirals remains in force.
