 Overseas advice on preventing SARS

The fact of the mysterious pneumonia has been widely spread in HK drives me to do a literature review on the suspected cause (i.e. corona virus) of the SARS (Severe Acute Respiratory Syndrome). As a biomedical researcher, let me show you my concern and make the following suggestions.


 The basic mechanism of viral attack is that the viruses replicate themselves using the host's (in this case is "our") DNA genetic replication system. By doing this, our body couldn't function well due to the massive viral replication. Supposing, the immune cells in our body will fight off the infected viruses quickly. However, the viruses are so smart that they could be able to produce some chemical  ubstances to cause our immune cells to die. Besides, this corona virus is a new kind of virus which belongs to a mutated strain and our body cannot recognize it. No antibiotics have been proved to be 100% effective in treating viral infection so far. The only effective way to get rid of it is by ourselves.  It likes a prolonged battle between the viruses and our immune response. In fact, viruses couldn't kill all the immune cells in a health individual. The stronger the immune function you have, the less the viral injury you get. Therefore, the degree of sickness after infection and the rate of recovery mainly depends on how strong your immune function is.



 You cannot avoid the infection unless you avoid from those infected individuals/area. But, you can try your best to boost up your immunefunction by several regimes. Make sure you are "extremely healthy" at least during this critical period. Stronger immune function could keep the viral damage minimal even you were so unluckily being infected. Also, stronger immune function delays the onset of any detrimental effects from the viral infection. Scientists are now working on tracking the treatment and so make sure you are still surviving until an effective treatment occurs. The following suggestions aim to strengthen your immune function within a short period of time.



 Antioxidant nutraceuticals: Antioxidants are chemicals found in foods which exert a great value in strengthening our immune system. Boost up your immune function by taking a cocktail of antioxidant supplements.



 Vitamin E 1000 IU per day.  Alpha-tocopherol is the biological active form of vitamin E. There are two forms of it: d-tocopherol and dl-tocopherol. d- is the natural form and dl- is the synthetic form.  Try
to get the d- form because it is absorbed faster in our body.
 l )  Vitamin C (ascorbic acid) 1000 milligram (mg) daily. Instead of taking supplement, you can take 2 pieces of citrus fruits (e.g. orange) a day to get the vitamin C
* Beta-carotene, not more than 10000 IU daily
* Selenium, 200 microgram daily
* Zinc, not more than 500 milligram (mg) daily
* Lipoic acid, 50 mg daily
* Glutathione, 50 mg daily
   No any adverse effects have been reported from the above suggested supplementation dose.

 1) 每天服用維他命E1000 IU (醫學國際單位,international units)
維生E是一种生物活性維他命E。它有兩种形式﹕d-維生素Edl-維生素E. d- 生素E是自然形式 dl-維生素E是合成形式。最好服用d-維他命E,因為它可以更快的被我們的身体所吸收。

* Beta胡蘿蔔素,每天服用不超過10000IU


 2)  * Let green tea to be your daily beverage because it contains tremendous amount of antioxidant flavonoid, catechins. * Eat more tomatoes, broccoli or fruits and vegetables in red and dark green color. They carry a huge amount of antioxidant carotenoids, lycopene and carotene.

 2)* 每天喝綠茶,因為綠茶中含有大量抗氧化劑類黃酮和茶酸。* 多吃蕃茄,花椰菜,和其它紅色和深綠色的水果,它們含有大量的抗氧化素如胡蘿蔔素。


 3) No intense physical activities during this critical period! It has been shown that intense exercise will suppress your immune function (related to the upper respiratory infection) even several days following your workout.
Instead of intense exercise, light-to-moderate workout helps if you have been training regularly.



4)Make sure you get enough carbohydrate foods (e.g. rice, food concentrated in starch... etc) because carbohydrate is the primary food for immune cells . Do some Gatorade or Pocari if needed since they are both good sources of carbohydrate.

 4) 確保你食用足夠的碳水化合物食物(例如,大米及其它富含澱粉的食物),因為碳水化合物是免疫細胞最重要的食物。喝一些Gatorade(一种飲料)或Pocari(一种飲料),因為他們都是富含碳水化合物的飲料。


5) Make sure you get enough sleep and don't make yourself so stressful! Anxiety, depression, and tired will influence your body's stress hormones (e.g. catecholamine and glucocorticoids) and so suppress your immune status.

 5) 每天保證充足睡眠,不要使自己處於緊張和壓力之下。焦慮、緊張及疲倦都會影響身体的壓力荷爾蒙(例如,儿茶酚氨和糖皮質激素)從而壓抑身体免疫功能。


 6) Mouth-mask helps despite it is not 100% effective. But it can still decrease the chance from infection.

 6) 口罩雖然不能100%預防感染,但是能夠起到一定的作用,仍然可以減少被感染機率。


 All the above information are supported by peer-reviewed biomedical literatures, that means they are credible and reliable! God bless and I really hope that none of you will get infected and I will pray for all of you in every moment!



Good luck and take extremely care.
