South Korea reports first case of “Centaurus” COVID subvariant-Chosun Ilbo: Daily News from South Korea

South Korea has identified the first case of a new highly infectious Omicron variant, Centaurus called BA2.75.

The Korea Disease Control and Prevention Agency said Thursday that a self-reliant man in his 60s at his home in Incheon was found to be infected with Centaurus.

It is still unknown where and how he was infected, but authorities must have already been active in South Korea as he has never traveled abroad during the period in which he may have been infected. I don’t think so.

BA.2.75 is a derivative of the BA.2 stealth omicron variant. It was first detected in India on May 26 and spread so rapidly that it already accounted for 51.35 percent of all Indian variants a month later.

To date, approximately 119 cases of Centaurus have been reported in 10 countries, including Australia, Canada, Germany, Japan, New Zealand, the United Kingdom and the United States. The dominant stock in South Korea.

The new subvariant was called Centaurus by Twitter users for no good reason, after a distant galaxy and a Greek mythical creature that is half human and half horse.

With the COVID virus, the peplomer first contacts the surface of the human cell, and mutations occur in this area, making it easier for the virus to invade the cell and make it easier for the strain to spread.

There are 36 spike gene variants in BA.2.75, but 28 in the BA.2 stealth omicron variant, which is thought to be 30 to 50 percent more contagious than the original BA.1 omicron variant. .. This suggests that the virus can bind cells more easily and avoid antibodies formed by vaccines or natural infections.

However, according to local media, many Indian patients infected with the new strain are asymptomatic or mild.

The new strain may exacerbate the current outbreak of infection, as the daily aggregate of new COVID cases has recently doubled to about 40,000. It was 38,882 on Friday morning and remained around 40,000 for four consecutive days.

“The endemic COVID will arrive next spring,” said Lee Jing-ko, a professor at Hallym University Kannam Sacred Heart Hospital, if the current trend continues. “The current resurgence does not bring new daily infections to 600,000 like the previous surges in February and March. If the pandemic surges again next spring, from 200,000 at worst. It can reach 300,000, then gradually weakens and becomes endemic. ”

However, Kim Woo Joo of Guro Hospital in South Korea said, “The virus mutates every six months and survives, and people are vaccinated and treated to fight it. However, we are still on the road from a pandemic to an epidemic. When the epidemic stage arrives. ”
