There are many reasons to be cautious about the 'natural immunity effect' that an infected person will give you now that there are many infections, but among them, the Stealth Omicron, which has stronger transmission power, is spreading recently.



Reporter Jeong Da-eun looked at whether the existing treatment was effective, although it is expected to become the dominant species in Korea next week and the peak will be longer.

Currently, the domestic market share of Stealth Omicron jumped to 41.4%.



The current trend is likely to be the dominant species for over half the next week.



It is also spreading abroad, but the number of confirmed cases is different.



In the United States, the share last week was 23%, but the number of confirmed cases is not increasing significantly.



On the other hand, the number of confirmed cases in the UK, which has exceeded 80%, and France, where it is at around 48%, has turned to an increasing trend.



The government predicted that the peak period would be longer if the stealth omicron becomes the dominant species.

Severity or hospitalization It is known that there is not much difference in the rate from the existing Omicron.



[Lee Geun-hwa/Professor of Microbiology at Hanyang University: When you look at the mortality and hospitalization rates in countries where stealth omicron is the dominant species, there is no difference compared to when omicron was prevalent.]



Journal of the American Medical Association of Massachusetts If you look at it, "A drug that didn't work for Omicron may work for Stealth Omicron, and vice versa."



In a study at the University of Washington in the US, there is also a result that Ibushield, a treatment for immunosuppression, is effective against Stealth Omicron.



The quarantine authorities believe that both Paxrovid and Lagevrio will be effective against Stealth Omicron.
