How to Prevent H1N1 - Best Advice So Far （如何预防H1N1 - 目前最好的忠告）
Friends,
Thanks to media hype about H1N1, several people who trust me have either approached or called me to advice. The hype in media about the utility of face masks and N95 respirators as a tool for general protection against H1N1 can't be deplored enough. Yesterday, a friend who listened wanted me to write down briefly what I advised so that he could tell others in similar words. Hence this short email to friends whom I have advised recently (and others whom I haven't yet).
Please realize that this is not an official advice, especially the one about face masks
or N95. Most N95 respirators are designed to filter 95% particulates of 0.3µ, while the
size of H1N1 virus is about 0.1µ. Hence, dependence on N95 to protect against H1N1
is like protecting against rain with an umbrella made of mosquito net.
大部分N95口罩的设计是过滤95% 的0.3µ微粒,，而H1N1病毒的大小是0.1µ 左右．所以，靠N95口罩防H1N1就像用蚊帐网做的雨伞挡雨．
Tamiflu does not kill but prevents H1N1 from further proliferation till the virus limits
itself in about 1-2 weeks (its natural cycle). H1N1, like other Influenza A viruses, only
infects the upper respiratory tract and proliferates (only) there. The only portals of
entry are the nostrils and mouth/ throat/eyes. In a global epidemic of this nature, it's
almost impossible not coming into contact with H1N1 in spite of all precautions.
克流感不杀H1N1 ，它只防止病毒扩散大约1-2周（它的自然周期）．
H1N1，跟其他Ａ型流感的病毒一样，只感染上呼吸道，并在那里扩散．病毒的唯一入口是口鼻喉．在这种本性的全球流行病疫中，幾乎所有防範努力都无法避免与H1N1接触．
Contact with H1N1 is not so much of a problem as proliferation is.
接触H1N1不像H1N1扩散问题那末严重．
While you are still healthy and not showing any symptoms of H1N1 infection, in order
to oprevent 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):
为了防止扩散和第二次被感染的症状加剧与发展，在你还健康与没有任何H1N1
感染症状时，可以做下面的几个非常简单步骤（而不是聚焦于N95与克流感的囤积）：
1. Frequent hand-washing (well highlighted in all official communications).
常洗手
2. "Hands-off-the-face" approach. Resist all temptations to touch any part of face
(unless you want to eat or bathe).
「手离脸」方式．（除了要吃東西与洗澡外），抗拒所有用手接触脸部任何部分的冲动．
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.
每天用温盐水（可用Listerine漱口水替代）漱口二次．首次感染，二／三天后H1N1在後鼻腔开始扩散与显示特定症状．漱口防止扩散．健康人的漱口与病人用克流感的效果是一样的．
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.
每天用棉签沾温盐水清鼻孔至少一次与用鼻子用力呼气一次，对降低滤过性毒菌数量是很有效的．
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.
吃富维他命Ｃ的食物以增强免疫力．如果需要用维他命Ｃ药片补充，確認它含锌（以加强吸收）．
6. Drink as much of warm liquids 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.
尽量多喝温水．喝水会将扩散病毒从喉洗到胃里．病毒一旦到胃裡就不能生存、扩散、与造成伤害．
7. All these are simple ways to prevent, within means of most households, and
certainly much less painful than to wait in long queues outside public hospitals.
所有这些都是简单的预防方法，在每个家庭都做得到的，比在公立医院外面排长龙的痛苦要少很多．
Happy breathing!
