Delta mutation with high transmission and fatality rate, unvaccinated 'much at risk'

<Anchor>

Let's summarize with Cho Dong-chan, a medical reporter, what is the most urgent thing right now with the Corona Virus that is almost impossible to catch

[Cho Dong-chan / medical reporter (specialist): There are two types. Diffusion rate and delta shift increase, let's see right away. This is a graph of daily patients in the UK and Korea, with 30,000 confirmed cases per day. Compared to the UK, Korea looks good. However, when comparing the diffusion rate using a mathematical function, it is very fast as shown in the figure on the right, Korea. Let's look at the change in the share of domestic delta mutations. The sky blue is the delta mutation, and it's growing rapidly. The rate of spread itself is fast, and the delta mutation with high transmission power is also increasing, so we are in a hurry to step 4.]

[Cho Dong-chan / Medical reporter (specialist): On the afternoon of the 8th, an official from the quarantine authorities called and said that there is something more fearful than the increase in the number of young patients. About 2 million people over the age of 60 in Korea have refused the vaccine and are currently unvaccinated. I told them that the spread of the delta mutation was my biggest concern. The government is adhering to the principle of vaccination in the fourth quarter of this year, which is the lowest priority for 1.66 million people between the ages of 60 and 74 who have rejected the AstraZeneca vaccine.]

[Cho Dong-chan / Medical reporter (specialist): The World Health Organization recently announced that the delta mutation has a high fatality rate as well as its contagious power. Let's take a look at the UK data. Of those infected with the alpha mutation from the UK, 2.1% died, compared to only 0.3% of those infected with the delta mutation. In the UK, there are a lot of people who have been vaccinated, so the fatality rate for the delta mutation is actually lower. This means that if you don't get vaccinated, you're much more at risk. There are 1.66 million elderly people who will receive the risk of delta mutation if not vaccinated, so it is not a situation to talk only about principles.]

[Cho Dong-chan/medical reporter (specialist): The effect of distancing will appear after a week to ten days. So, if you do it once, it should be done for at least 2 weeks. During this period, it seems that the 4th stage can be solved only if the number of daily confirmed cases is reduced to less than 800.]
