"herd immunity is impossible"... What is the condition of 'coexistence with Corona'?

<Anchor>

Those of you who have seen Heung-Min Son's game these days may have felt it, but in England, tens of thousands of confirmed cases a day, people do not wear masks on soccer fields.

In addition, although the corona virus remains in Denmark in Europe, people do not keep distance and live without masks. After the UK declared coexistence with the coronavirus for the first time in the world, Denmark and Singapore followed suit. One thing they have in common is that the vaccination rate is high, but the level of recovery to normal life varies from country to country. We now have around 2,000 patients a day, so quarantine is important right now, but in order to return to our daily life someday, it is also a time when we need social concerns about how to live with Corona.

First, we will listen to the explanation of medical reporter Dong-chan Cho, and then we will continue the story.

Is herd immunity possible, in which the majority of society members become immune to Corona and no longer be infected?

This is a graph that calculates herd immunity.

If one confirmed person infects 2 people, 50% of them get the vaccine to reach herd immunity, and if 1 person infects 5 people, 80% gets it.

However, delta mutation seems to be possible if one person infects 6-7 people and gets more than 80-90% of the vaccine, but there are variables.

Herd immunity is not calculated even if the vaccine is 100% correct because the effectiveness of two doses of vaccine is only 50% in the UK and 60% in the US.

The delta mutation made herd immunity impossible.

Serious side effects can follow if strong distance continues for a long time.

As a result of a survey by the British Health Service, depression and anxiety indexes rose significantly, and in a domestic survey, more people were thinking of extreme choices.

[Baekjongwoo / Kyunghee University Hospital, Mental Health Department, Professor. The additional measures about mental health issues is essential because of low income or collective lack to receive women and help resources can be in more trouble -

so claimed 'Corona and coexistence "is It's getting bigger.

Let's accept the number of confirmed cases and restore our pre-coronavirus life.

It is not announcing the number of confirmed cases every day, but lifting the limit of business hours and number of gatherings.

In Korea too, once most of the high-risk groups have been vaccinated, they should seek coexistence with the coronavirus in stages.

For more details, let's talk a little bit more with Cho Dong-chan, a medical reporter.

[Cho Dong-chan / Medical reporter/specialist: Yes, a professor at Harvard Medical School in the United States recently announced through the media that the number of cancer patients in the United States is decreasing. He warned that it would appear after 4 years. It was predicted that if diagnosed early, cervical cancer patients who can survive for more than 20 years may die within 3 to 4 years. people, a decrease of 19%. If you look at colorectal cancer and university hospital B, 3,600 people were diagnosed in 2019, but last year it was only 3,000. It is a clear danger signal, and for this reason, it is said that it is impossible to postpone the current medical system centered on confirmed cases to pre-COVID.]

[Cho Dong-chan / Medical reporter/specialist: Yes, right now, we are preparing beds and disposing of medical personnel according to the corona confirmed patients, but we are going to change it to Corona severe. What you see is a list of medicines prescribed to patients with mild symptoms at the Living Treatment Center. Most of them are medicines that can be taken at home, such as a runny nose, cough medicine, and digestive medicine. Ninety out of 100 corona patients are mild, but they are being treated at home, and concentrating medical resources on critically ill patients is the coexistence of the medical system.]

[Cho Dong-chan/medical reporter/specialist: Yes, social distancing, vaccines, treatment drugs, the strongest thing that suppresses Corona is the mask. So even if quarantine measures are gradually eased, taking off the mask will be the last thing. However, if the corona flu at any age fell below the level, for example, if it can heal better about eating five days early in the development it seems to be able to take off the mask.
