The number of South Koreans who have tested positive for Covid-19 in relation to the Consumer Electronic Show (CES) in the US jumped to 119 on Thursday.
Ko Jae-young, spokesman for the Korea Disease Control and Prevention Agency (KDCA), said some of those who tested positive carried the Omicron variant, without giving specific numbers.
In a press release, South Korea's health ministry urged attendees who were exempted from quarantine to work from home for 10 days to prevent spreading the virus.
On Thursday, South Korea reported 391 imported Covid-19 cases, a daily record, according to KDCA.
In response, South Korea will mandate that international arrivals take a PCR test within 48 hours of departure -- shortened from 72 hours -- starting from January 20, Ko said.
Health authorities estimate that the Omicron variant may become the dominant variant in the country by late January, Ko said.
Starting from Friday, South Korea will also begin administering Pfizer’s oral treatment pill Paxlovid to patients with a high chance of getting critically ill, those aged 65 or above, and those with reduced immunity, KDCA said in a press release.
The country reported 4,167 new cases from Wednesday, bringing the total confirmed cases to 679,030, KDCA said. The death toll rose by 44 to 6,210.
