South Korea on Tuesday saw a record-high number of new infections.
The country logged 8-thousand 5-hundred 71 new COVID-19 caseswhich was up by nearly 4-thousand 5-hundred from a week ago.
This is the first time the country has seen daily figures surpass the 8-thousand mark and officials are attributing it to the rapid spread of the Omicron variant.
The Omicron strain is now dominant, taking up more than half of all cases nationwide.
Regions like Honam, Gyeongbuk and Gangwon particularly have been hit the hardest.
8 out of 10 infections in the Honam region were Omicron.
Gyeongbuk has identified nearly 70 percent of all cases as Omicronwhereas for Gangwon, this number is nearly 60 percent.
Omicron is also responsible for a breakout of cluster infections in the greater Seoul area.
It's responsible for nearly 90% of all cases in Pyeongtaek city, Gyeonggi-do province and is rapidly spreading due to cluster outbreaks at a U.S. military base and a nursing home.
During a briefing on Monday, KDCA commissioner Jeong Eun-kyeong cited domestic data which proved booster shots play an effective role in fighting against this variant.
"We've seen how many neutralizing antibodies one could build after getting a booster shot, or a third extra jab. It turns out, a booster shot can increase antibodies against Omicron by up to 100-times."
To further tackle the variant, South Korea is set on launching Omicron-tailored prevention measures on Wednesday.
The new virus strategy will focus on effectively utilizing limited medical resources.
COVID-19 testing centers will start testing only high-risk groups and suspected infections with a PCR test.
Everyone else will have to test themselves using rapid antigen test kits.
The latest measure will first kick off in Gwangju, Jeollanam-do, and Pyeongtaek city and Anseong city in Gyeonggi-do province from Wednesday.
The new testing method will be expanded nationwide as early as the end of this month or the beginning of February.
There will also be a change in the number of days fully vaccinated patients must remain in isolation.
This period will be shortened to a week down from what was originally 10 days.
