As the corona virus continues for more than two years, it has become a natural thing to wear a mask when going out of the house.

The government said that it would consider using the mask, which has become a symbol of Corona, only indoors, but let's see if that's okay.



This will be reported by Cho Dong-chan, a medical professional reporter.

The start of corona prevention was a mask.



There were times when she had to stand in line on set days and only buy a few.



There are many different views on the obligation to wear a mask.



[Jin Han-byeol / Yangcheon-gu, Seoul: I think it is good to take off the mask outdoors and expand your lifestyle a little bit.]



[Kyung-hee Cho / Yangcheon-gu, Seoul: There are many benefits of masks, aren't there?

The number of cold patients is also decreasing, so I'm still using it...

Most coronas are transmitted by large droplets of saliva that fall within two meters.

The mask blocks these large droplets of saliva.



Outdoors, saliva drops do not collect much, but scatter.



So the risk of infection is low.



It means you can take off your mask as long as you keep your distance.



Indoors, on the other hand, these droplets are less scattered and the risk of infection is greater.



This is why you need to ventilate often.



Is the current trend of Omicron different?



Even with the same mask, Omicron has a stronger radio wave than Delta.



By the way, when you take off the mask, the propagation power of Omicron is much stronger than Delta.



Let's look at the prevention rate by mask.



Cloth masks were the lowest at 56% and N95 masks like our KF94 had the highest at 83%.



This time, let's look at the mask report from the US Centers for Disease Control and Prevention.



Masks interfered with language and emotional development in children, and created a sense of isolation in adults.



Although the advantages of masks and quarantine are great, there are also obvious disadvantages from a social point of view.



Following the UK and Denmark, India also does not mandate outdoor masks, but indoor masks are recommended.



There are also opinions that it should be solved in stages.



[Choi Jae-wook/Professor of Preventive Medicine, Korea University: Wearing a mask in high-risk facilities, that is, medical institutions, nursing hospitals, or spaces where special vulnerable groups live, is mandatory for the time being, but for other general multi-use facilities, it is recommended. Switching (I hope)]



An official from the quarantine authorities said that the biggest variable in the mask policy is public opinion.
