HPS Weekly National Influenza Report - week ending 17 December 2017

In week 50, influenza activity is increasing in the community and in closed settings, with clinical and virological indicators both higher than in the same period for the past four seasons. This season there has been earlier reporting of closed setting outbreaks of influenza compared to the last three seasons. Community circulation of influenza has prompted the issue of a CMO letter advising that GPs may prescribe antivirals.
