經免疫學博士研究發現市場最暢銷的口罩是無法預防SARS的!!
很多人認為戴上口罩會比較安全不容易感染SARS. 然而, 試問戴上口罩真的有其效果嗎?
你可知現在最暢銷N95口罩透氣孔的大小為何? 答案是0.3微米.你可知造成SARS的冠狀病
毒實際只有0.06微米? 也就代表即使是N95也無法防堵冠狀病毒入侵我們的身體! 伊拉克
為了防止化學武器的傷害,運用完善的防護裝來保護他們自己以及使用氧氣筒來呼吸, 這
樣的裝備才能真正的防止冠狀病毒的入侵.
事實上, 戴著口罩同時又說話時會將唾液及其它的分泌液體沾附在口罩上, 這樣會造成一
個適合細菌及病毒生長的環境. 讓我們來了解冠狀病毒傳播的方式, 當一位SARS病患觸摸
他的鼻子或者用他的雙手覆蓋他的嘴巴, 他的手就會充滿了冠狀病毒. 所以當他去辦公室
觸摸辦公桌或是門把, 他就將冠狀病毒給留在他所觸摸過的地方(離開宿主,冠狀病毒只能
生存三小時).這時若有人接觸了這些地方後, 又用手去揉眼睛或拿食物, 冠狀病毒就直接
侵入了那個人的體內. 接著病毒將會釋放它的DNA於人體的細胞並開始進行複製,這時我們
體內免疫系統(干擾素 - 不知正確專業名詞為何)會啟動並阻止病毒細胞的複製,我們體內
的(白細胞介素不知正確專業名詞為何)會聚集白血球及抗體來抵抗病毒. 當這場體內的戰爭結束後, 我們的身體將會再一次的自動複製自身的細胞, 而這是藥物無法做到的.
現在你知道你的免疫系統是如何作用並保護你免於感染SARS或是其他的病毒攻擊了. 所以
請保持穩定的情緒, 足夠的休息, 多運動及均衡的營養來好好照顧你的身體並使它強壯!
另一個有效預防SARS方式就是經常洗手, 因為病毒的外在保護體是非常脆弱的, 所以運用
肥皂及水就可破壞它的保護體使它無法生存.

I have learnt more about SARS and I would like to share with you. ( Dr Chen's
expertise is in Immunology)
A lot of people wear mask as they think that it is a lot safer to do so.However
,did you ever ask yourself whether is it effective or not? Do you know the po-
re size of the best selling mask N95 nowadays? The answer is 0.3 micron.
Do you know that corona virus which causes SARS actually size 0.06 micron?
Ha, this means that even the N95 is a large doorway for corona virus to invade
into our body! Iraqis in order to prevent chemical weapon, cover themselves
so well with protective suits which they need to pump oxygen so that they can
breath.
Well, that type of protective suits can really prevent corona virus to invade
into our body!
In fact, wearing masks and talking at the same time will cause fluid and saliva
to gather on your masks. This will then create a very good environment for
bacteria and virus growth.
OK, let's understand how corona virus spread. When a SARS patient rub his nose
or cover his mouth with his hand, his hand is full with corona virus. When he
go to the office and touches the table or door knob, he leaves the corona virus
on it (Corona can survive for only 3 hours outside host cell). When a person
touches the table or door knob, she will then pick up the virus on her hand.
If she rub her eyes with her hands or take food using her unwashed hands,
corona virus will invade into her body.
The virus will then inject DNA into our cell and start replicate. Our immune
cell - Interferon in our cell will trigger the infected area to stop replicat-
ing. Whereas another immune cell - interleukin will gather more white blood
cell, antibodies to the infected area and fight with virus. Once the battle
is over, our own body cell will start replicating again automatically. This is
what drugs cannot do.
Now you know how your immune system work for you and prevent yourself from getting SARS or whatever viral infection! Thus take very good care of it and strengthen it through stable emotion, good rest, good exercise and balanced diet!
Another effective way to prevent one from getting SARS is to wash you hands frequently. Virus is protected by an outer layer which is quite fragile. We can wash our hand with soap and water, the outer layer will break and
virus can't survive.
Please convey the message to your family and friends.
