The only portals of entry are the nostrils and mouth/throat. In a global epidemic of this nature, it's almost impossible to avoid coming into contact with H1N1 in spite of all precautions. Contact with H1N1 is not so much of a problem as proliferation is.
While you are still healthy and not showing any symptoms of H1N1 infection, in order to prevent proliferation, aggravation of symptoms and development of secondary infections, some very simple steps, not fully highlighted in most official communications, can be practiced (instead of focusing on how to stock N95 or Tamiflu):
Frequent hand-washing (well highlighted in all official communications).
Neti pots and sinus rinse kits are available at the drug store and relatively inexpensive under $15.
"Hands-off-the-face" approach. Resist all temptations to touch any part of face (unless you want to eat, bathe or slap).
Gargle twice a day with warm salt water (use Listerine if you do not trust salt)...
H1N1 takes 2-3 days after initial infection in the throat/ nasal cavity to proliferate and show characteristic symptoms. Simple gargling prevents proliferation. In a way, gargling with salt water has the same effect on a healthy individual that Tamiflu has on an infected one. Do not underestimate this simple, inexpensive, and powerful preventative method.
Clean your nostrils at least once every day with warm salt water.
Not everybody may be good at Jala Neti or Sutra Neti (very good Yoga asana to clean nasal cavities), but blowing the nose hard once a day and swabbing both nostrils with cotton buds dipped in warm salt water is very effective in bringing down viral population.*
Boost your natural immunity with foods that are rich in Vitamin C (Alma and other citrus fruits).
If you have to supplement with Vitamin C tablets, make sure that it also has Zinc to boost absorption.
