Five more cases of the new subvariant of the Omicron strain have been discovered in Korea. The first was found here on May 3, bringing the total to six.
The government Tuesday said an epidemiological investigation is under way. The six people infected with BA.2.12.1 arrived in Korea from the U.S. between April 16 and 24 and tested positive the day after arrival. Five of them were triple-vaccinated and one had two jabs.
Two had no symptoms, while the other four suffered from sore throats, coughing and ear aches. They came into contact with 17 others, including their family, but no further cases have been found so far.
The so-called New York subvariant was first discovered in the U.S. in December last year. It is thought to be about 30 percent more contagious than the original Omicron variant, and responsible for the latest surge in COVID cases in the U.S.
One health official said, "It's the most troubling subvariant right now, but there is no difference in severity, so we don't believe it will lead to higher fatality rates."
No further cases have been found of the XQ, XE and XM variants that were also discovered here, and cases of the South African B4 and B5 variants appear to be limited.
On Wednesday morning the daily tally of new coronavirus infections stood at 43,925.
