Today (the 4th), the number of new corona cases is expected to reach 40,000.

While the gradual decline continues, a mutation with stronger radio wave power than the existing Stealth Omicron was confirmed for the first time in Korea.

This is Correspondent Han Seong-hee.


Last week, the average daily number of confirmed cases was 58,000, down 34% from the previous week.

Both severe cases and fatalities decreased by 32%.

[Lee Sang-won / Head of Epidemiological Investigation and Analysis Team, Central Quarantine Countermeasures Headquarters: Weekly new confirmed cases have decreased for 6 weeks in a row.

I think the downward trend will continue for more than a month.] With a

clear downward trend, the risk level fell to 'medium' in 15 weeks in the non-metropolitan area following the nationwide and metropolitan areas.

The quarantine situation is stable, but the variable is the emergence of new mutations.

Stealth Omicron, which has 20% more propagation power than Omicron, and a new sub-mutation known to be 27% stronger than Omicron, was first identified in Korea.

A woman in her 50s who had completed the third dose was confirmed after arriving from the United States.

[Park Young-joon / Head of Epidemiological Investigation Team, Central Quarantine Countermeasures Headquarters: No clinically unusual situations have been reported for the condition of the infected.

Investigations into the suspected infection are currently underway...


It has not been confirmed whether it is more toxic, but in the United States, where this mutation is spreading, the number of confirmed cases increased by 70% last week from a month ago.

In South Africa, another omicron sub-mutation BA.4 and BA.5 is prevalent, and the number of confirmed cases has increased 7-fold in one month.

Studies have shown that these mutations also evade immunity formed by infection or vaccination.
