There's some amazing threads going regarding general prepping, plans, updates (Prepping for a pandemic threads in particular), my sincere thanks to those keeping us updated! 
As part of a family with several "high-risk" categories 
, I really wanted to start condensing information together in one place about what to do if/when you actually catch it - ie. preventative measures have failed, and providing you are well enough to be managed at home.
The Basics
Vitamin C & Vitamin D (immune support)
Paracetamol/ibuprofen - some finer details to consider about whether it might be better to allow fever to take its course.
Throat lozenges/difflam spray
Oral rehydration fluid/syringe
Olbas oil and/or Vicks vapour rub
Hot water bottle to keep on chest (aids vapourisation and increases blood flow to lungs).
Other things I'm currently looking into that may or may not be helpful
Oil diffusers & tea tree/eucalyptus (basically like olbas oil for symptom relief but possibly some anti-viral action also?)
Elderberry syrup products (ie. Sambucol) - strong antiviral action against influenzae viruses at least

I'd love to hear about anyone else's ideas or studies they've found - even if it's just "may be helpful" stuff.
I think I've maxed out on what I can do to minimise our chances of getting ill. Now I really want to prepare a plan about what to do/try if we catch it anyway.
