Influenza activity is increasing and there is evidence of circulation of influenza within the community and closed settings. This prompted the issue of a CMO letter in week 49 advising that GPs may prescribe antivirals.
A Scottish addendum to the Public Health England guidance on use of antiviral agents for the treatment and prophylaxis of seasonal influenza has been published on the HPS website.
