BigS, It seems you are already a good eater. Pound vitamin C if you got it.
Wash the place and keep washing it the whole weekend - discreetly of course. If you have lysol or similar, keep it handy and spray/wipe surfaces with it. Anti-bacterial soap for you hands and face. WASH OFTEN. Use mouthwash and gargle several times a day. And if you can, rinse you nose and nasal canal with just a saline solution. You asked.
HAPPY BIRTHDAY KZ!
