Kwon Aeri's friendly economy starts on Thursday. Reporter Kwon, it is now a life-prevention system, and starting next week, students will have a simple school. However, the school's instructions for prevention are not specific, so I am anxious. This is happening.

Especially before the school starts, students and parents are very interested, and yesterday (6th), I was told at the disease management headquarters briefing.

It's early May, but it's already hot. In some southern regions, daytime temperatures have already exceeded 30 degrees. So you might want to turn on the air conditioner sooner than you think, but you're worried about it.

First, Corona 19 should not propagate in the air. It is known that droplet droplets splash or bury to spread.

This is due to the concern that machines that clean the air by lowering the temperature by causing strong wind circulation or blowing air may have the effect of blowing off the droplets.

China, there have been reports of cases that may actually be due to air conditioning, which actually seem to be due to air conditioning?

<Reporter>

Actually, the virus seems to have spread from the air conditioner. There are cases of infection in China where the paper was published.

This is also the case mentioned by the head of the Centers for Disease Control and Prevention yesterday, a family who returned from a trip to Wuhan, China on January 23, to eat at a party in Guangzhou on the next day, the 24th.

It is family A who is seen in the middle of the picture now. That day, the first person in the family A to look at was tested for "Oh, my body is strange" and was infected.

Then, from February 5 to 1, the infected people among the B and C families who sat at the tables on one side for ten days, followed by the number of people who were present at the restaurant, now increasing to 10.

The B and C families on either side had nothing to do except to sit next to A in this restaurant. In table C, some people showed symptoms from the 27th, before January 27, before the second person in family A showed symptoms.

The distance between the tables was about 1 meter, and the overlapping time between the three families was about 50 and 70 minutes, respectively.

Researchers in China noticed that the air flow in and out of the air next to the C family overlapped the path of the virus spread.

Guangzhou is a hot area, so air conditioning was turned on in January.

As there have been cases like this, it is essential that the government set effective guidelines. First, yesterday, General Jung pointed out that this Chinese restaurant had no windows.

It means that ventilation is not properly done in a room with viruses. There was an exhaust fan on the wall on the side of family B that you just saw across from the air conditioner.

In order to start school, it is said that more positive ventilation is required when the air conditioner is turned on, but it is known that the air conditioner turns on the air conditioner with the windows of the classroom open with the advice of air experts.

Also, as the days get hotter and higher, the children will surely keep running. In this case, I think what to do with the mask again.

<Reporter>

Yes. In principle, the anti-virus mask is basically KF94. I told you a lot about using KF80 when you are very worried about ultrafine dust in a friendly economy.

In fact, the virus is actually not 80 to stop without leaking water.

However, yesterday, the Central Defense Response Headquarters announced that it was okay to use the KF80, and even a thin dental mask or dental mask.

Because, as a matter of fact, many people are familiar with it, KF94 is hard to breathe and frustrating enough to talk about hyperventilation in children.

So rather than being frustrated, I wrote, took off, touched, but in a normal environment, the KF80 could be better, and for the same reason, it would also be a dental mask. Than not.

If you are not in a situation where medical personnel care for patients who have a high degree of virus contact, it is a good idea to use a thin dental mask or KF80 without touching or removing it.

Now that distance has begun in life, there will be more examples and more questions in the future.

The government's plan is to release a modified version of the case by the end of this month to improve the detailed guidelines for keeping distance in your life.
