The only portals of entry for the virus 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 (well highlighted in all official communications).
2. "Hands-off-the-face" approach. Resist all temptations to touch any
part of face (unless you want to eat, bathe - or slap).
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
Neti but blowing the nose hard at least 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.
