가장 확실한 바이러스 자구책 ‘마스크’, 어떻게, 왜 사용해야하나
Wearing a mask and washing your hands are the most effective ways the public can help prevent the spread of the coronavirus.
But with so many types of products on the market, it can be confusing for consumers.
Lee Kyung-eun provides some important tips.
The coronavirus outbreak has triggered a nationwide rush for masks in South Korea.
Drug stores, supermarkets and even online stores,… are struggling to keep up with the skyrocketing demand.
“I’ve tried lots of places but they were all sold out.”
“Now because of the new Chinese virus, mostly all the masks in my district are sold out.”
And lots of customers are looking for a particular type of mask.
“Many people ask for disinfection masks that have the KF label – the 80, 94, and 99.”
The numbers of the KF or Korea Filter masks show their filtering ability.
The KF80 can filter more than 80 percent of particles that are 0.6 micrometers or larger.
The KF94 can block 94% of particles that are as small as 0.4 micrometers, and the KF99 can block 99% of these particles.
But experts say, when it comes to preventing the infection of the novel coronavirus,… it doesn’t matter which type of mask you use because the virus spreads through large droplets.
“The virus doesn’t come out itself. It comes out surrounded by saliva when you cough. And those droplets are bigger than 0.5 micrometers, which can be filtered by most general or medical masks. In fact, it is hard to breathe through masks with high KF numbers, so people are prone to taking them off.”
“Experts say how you wear your mask is more important. The mask should tightly cover your face and nose, and you should adjust it so that it fits the shape of your nose.”
Experts say wearing a mask can also help prevent secondary infection.
“You also have to be careful about the secondary or indirect infections from someone’s droplets,… meaning you pick up the virus by touching an object with your hand and then touching your face. But wearing a mask can lower the chances of that happening.”
To make sure that people have no problem getting hold of masks,.. the government announced on Thursday that people can report illegal trading activities to the Ministry of Food and Drug Safety.
