The fifth wave of the epidemic continues to worsen. It is reported that today (11th) the number of confirmed cases has broken and reached a new record high.
Masks have become the key to preventing citizens from getting sick. Earlier, Professor Yuan Guoyong had urged citizens to wear two masks.
Dr. Lam Shun Chiu also produced and uploaded a short video to teach citizens to make high-efficiency masks.
In the film, he successively introduced three methods to improve the protective ability of masks. Among them, the method of using a stapler to staple both sides of the mask can better prevent the mask from leaking, and the protective ability of the mask has been greatly increased from 45% to 90%, which greatly reduces the amount of air leakage. chance of recruiting.
Dr. Lin Shunchao taught people to make high-efficiency masks.

Lin Shunchao said that surgical masks, N95 masks and cotton masks are the three major types of masks currently on the market.
Cotton masks are the least protective of the three types of masks and do not have any ability to filter viruses.
Surgical masks have three layers, and the middle layer is used to filter viruses, which can filter 95% of viruses.
But when people wear masks, their protection is less than 45% because air leaks on both sides of the mask.
Relatively speaking, N95 masks have the strongest protection ability, can filter 99% of viruses, and can be covered even when worn, so the protection ability exceeds 99%.
However, some citizens may not have such masks in their homes.
Lin Shunchao pointed out that even if there is no N95 mask, there is no need to be afraid. By optimizing the surgical mask, the protection of the mask can be improved.
The cotton mask can cover the gaps on both sides to prevent the mask from leaking.

Method 1: There are gaps on both sides when wearing a surgical mask, you can wear an extra cotton mask to cover the gaps on both sides, so that the mask will not leak.
Knot the sides of the surgical mask to improve air leakage.

Method 2: Knot both sides of the surgical mask to improve air leakage.
Use a stapler to staple both sides of the mask to make the mask close to each other.
Pay attention to the skills of nailing the mask, first fold it at the iron line, and fold it to 90 degrees.
When nailing, do not nail the nail feet inward, otherwise it will easily scratch your face.

He pointed out that the third method is the one that he personally recommends the most.
Lin Shunchao added that many experiments have been done to prove that this method is the most veneer.
He continued that the simple method of making high-efficiency masks can make the virus filtration capacity of surgical masks change from less than 45% to more than 90%.
He admitted that now is an extraordinary period, and the Omicron epidemic has a chance to get completely out of control.
I hope everyone will work together to use high-efficiency masks when going out.
He said that Omicron usually has an onset period of three to five days, and some can be as long as 14 days.
If citizens wear it for two weeks, on the one hand, they will avoid spreading the virus, and on the other hand, they will not be recruited.
There is definitely a chance to reverse the current Omicron epidemic situation.
