對抗肺炎病毒「洗臉很重要」！（大家可以分享）

美國專家說：「對付武漢肺炎病毒，要常常先洗淨手，再用已洗淨的手洗臉，包括嘴巴、鼻孔、眼睛及耳朵等等病毒會侵入之處，不要光洗手而已。」以上「洗臉重要」的方法可供參考。

剛剛國內一位有名的劉醫師告訴我說：「確是如此。記得用肥皂，加上沖水超過一分鍾。才能帶走細菌、病毒。」

以下是科學的解釋。

如果在先洗手後洗眼睛的淚腺處、鼻孔，嘴巴和耳朵，從而去除了90％的病毒顆粒，那將大有幫助。 其原因之一是較低的病毒載量可使先天免疫系統中的巨噬細胞和嗜中性粒細胞輕易地吞噬並吃掉剩餘的病毒顆粒。

如果您不這樣做，並且讓大量病毒顆粒進入體內，則會使先天免疫系統超負荷工作，您將不得不依靠自己的天然適應性免疫系統，這需要三天左右的時間由基因進行專門設計出的抗體，以摧毀該病毒。 其方法是通過鎖定病毒外殼上較脆弱的蛋白質打擊，以摧毀病毒。

這程序要復雜得多，消耗掉人體所需的能量，並花費很多寶貴的時間。

最好保持臉部清潔，並讓更少的病毒顆粒進入體內，而這些極少數顆粒只是會被嗜中性粒細胞和巨噬細胞的強力作用下所輕易消滅。

故洗臉很重要。

What is an important defense against the Wuhan coronavirus?

Facewashing!

First wash your hands, then use your clean hands to wash your face.

This is because most germs don't enter the body through cuts in your hands, but rather through the mucous membranes of your face, i.e. through your moth, nostrils, tear ducts and ears.

Much smarter than just washing your hands.

Please share with other people.

Here is the scientific explanation.

If you remove 90% of the viral particles by washing your tear ducts, nostrils, mouth and ears after first washing your hands, it can help greatly. One reason for this is that a lower viral load allows the macrophages and neutrophils in your innate immune system to simply devour and eat the remaining viral particles.

If you do not do this and a large number of viral particles enter the body, this overloads the innate immune system and you are forced to rely on your adaptive immune system, which takes three days or so to genetically engineer antibodies specifically designed to destroy the viruses by targeting vulnerable proteins on their outer coat.

That is far more complicated, drains the body of needed energy, and takes much precious time.

It is far better to keep your face clean and allow far fewer viral particles to enter the body where they are simply annihilated by the brute force approach of the neutrophils and macrophages.
