b) Email from Health Protection Agency came round work today - flu levels have risen so fast this year that we're now being advised to prescribe antivirals. If you get symptoms of flu (sudden onset headache, fever, generally feeling like you're about to die), ring your GP and ask for some Tamiflu. Unless you had a flu jab this year of course, in which case you might be ok.
c) Local hospitals were fitting masks for medical staff this week, in case the "blip" turns into pandemic flu.
Merry Christmas...?
