I received an email on H1N1 prevention. Most of the info makes sense so take it for what it's worth.
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):
1.Frequent hand washing
2.Hands off face approach...keep hands away from face.
3.. *Gargle twice a day with warm salt water (use Listerine if you
don't 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. Don't underestimate this simple, inexpensive and powerful preventative method.
4. Similar to 3 above, *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 asanas 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.*
5. *Boost your natural immunity with foods that are rich in Vitamin C
(Amla and other citrus fruits). *If you have to supplement with Vitamin C
tablets, make sure that it also has Zinc to boost absorption.
6. *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
