As the government predicted, the number of corona patients continues to decrease and I hope that the day will come soon when we can return to our daily lives, but there is also unwelcome news.

Another corona mutation is appearing in other countries.

Medical reporter Yoo Seung-hyun covered what kind of mutations there are and how they will affect our lives in the future.

World Health Organization (WHO) announced in a report released on the 29th of last month that three new mutations, XE, XD, and XF, appeared.

XD and XF are a combination of delta mutation and omicron mutation, and XE is a mutation that combines omicron and stealth micron mutation.

WHO is paying particular attention to the XE mutation.

Since it was first discovered in the UK on January 19, 637 cases have been confirmed, and it has also been detected in Israel, Taiwan and Thailand.

The WHO said, "In the initial study, it showed an 'infection increase rate advantage' by about 10% compared to the stealth omicron.

Analysis of the severity of the disease and the fatality rate is not easy due to the lack of data.

[Bae Ji-yoon/Professor of Infectious Diseases at Ewha Womans University Mokdong Hospital: There are still few cases of (XE) mutations, so more data must be accumulated to determine whether the transmission power is higher than that of Omicron or Stealth Omicron and the fatality rate (a conclusion can be drawn)

] There are no cases of detection

"We are considering restarting social distancing by focusing on three factors: transmission power, fatality rate, and vaccination effect," the government said.

He said, however, that there is still no singularity to the extent of devising a new quarantine strategy.

We explained that we are different when it comes to having two peaks as the stealth Omicron re-emerges after the Omicron epidemic in some countries.

Stealth Omicron will quickly replace the existing Omicron, so the trend will be prolonged, but there will be no double peak of rising again.
