Let's organize the contents of Corona with Cho Dong-chan, medical reporter.



Q. What is the peak of the resurgence?



[Cho Dong-chan / Medical reporter (specialist): There are countries that have experienced a resurgence due to the sub-displacement of the Omicron, and there are countries that have not.

The UK and France experienced a resurgence after about five months of peaking, while Spain and the Netherlands have yet to see a resurgence as you can see.

Let's look at our graph.

Around March 20, the peak was 650,000 people a day.

It's on the rise now, but compared to then it's at the bottom.

The quarantine authorities are careful with the expression 're-fashion', as it is possible to take a box-bound move here.

If the normal thick line, 1,000 per 1 million population, and 50,000 daily confirmed cases per week on average exceeds 50,000, it can be said that it has entered the sixth wave.

The peak of the resurgence is from late August to mid-October.

The scale was estimated at 150,000 to 200,000, the quarantine authorities predicted.

This is a forecast calculated based on the prevalence of the epidemic in European countries and the vaccination rate in Korea.]



Q. What is the severity of the disease?



[Cho Dong-chan / Medical reporter (specialist): Let's look at this as well as the fatality rate graph in Korea.

The number of deaths is increasing and decreasing day by day, but on average, the number of deaths compared to the number of patients continues to decrease.

As of last May, the severity rate fell to 0.14% and the fatality rate to 0.07%.

In fact, it has dropped to the level of the flu, and the severity is similar.

But the more people get the flu, the more deaths.

Even with this BA.5 mutation, more than 90% of the deaths are from the high-risk group, so it seems that the early diagnosis and early treatment system should be checked.



Q. Is the 4th vaccination necessary?



[Cho Dong-chan / Medical reporter (specialist): First of all, today (12th), the quarantine authorities said that BA.5 transmission power is high, but there is a hidden meaning.

Since the radio wave power is strong, it is said that distancing will not be very effective.

It would be difficult to reintroduce ineffective and costly social distancing.

The vaccine would be good if a new white person that prevents mutations comes out, but Moderna seems to be in September at the earliest, and Pfizer is probably later.

It's a frustrating situation because the pandemic seems to be faster than the release of a new vaccine.

Then, the 4th vaccination must receive the existing vaccine, but the United States said that it would consider lowering it to the age of 30.

There were reports that we would expand to those in their 50s and those with underlying conditions, but the World Vaccine Alliance concluded that the effectiveness against the new mutation was still insufficient.

After all, the expansion of the 4th vaccination is a high-level policy.

Prevention should be focused on early diagnosis and treatment of high-risk groups.]
