Hi Jack,

The best ways that I know are:

- Good hygiene- wash your hands when you get in from being outside, before eating/touching food etc.
- Grape-seed extract capsules- may or may not work, but they help me feel more relaxed and should work if grape juice works!
- Foaming anti-viral hand sanitizer

I also have a supply of anti-emetic meds to take if I feel nauseated- perhaps ask your doc about these?
