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.

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 can be practiced

1. Gargle twice a day with warm salt water or Listerine. *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. Don't underestimate this simple, inexpensive, and powerful preventative method.

2. Blow the nose hard once a day and swab both nostrils with cotton buds dipped in warm salt water. This is very effective in bringing down viral population.

3. Boost your natural immunity with foods that are rich in Vitamins C and D. If you have to supplement with Vitamin C tablets, make sure that it also has Zinc to boost absorption.

4. Drink as much of warm liquids (tea, coffee, etc) as you can. Drinking warm liquids has the same effect as gargling, but in the reverse direction. They wash off proliferating viruses from the throat into the stomach where they cannot survive, proliferate or do any harm.
