9-fold rise reported in S. Korea COVID-19 cases, but there's good news

Seoul: South Korea is in the midst of a major Omicron new case surge, with nine-fold increase in new COVID-19 cases on Monday (February 7, 2021) compared to the mid-January data. Now, officials expect the country may see daily jumps of 130,000 or 170,000 by late February.

But there's some good news: so far, with high vaccination and booster rates, alongside other mitigation efforts, the number of ICU cases and deaths are significantly down, according to latest Our World in Data figures.

South Korea COViD-19 inflections jumped more than 9-fold since the beginning of February 2020, with new cases spiked from less than 50 to 500 per million people as of Monday. With high vaccination rate (86%) and booster shots at 58%; new ICU cases dropped from more than 20 per million to to less than 5.

Meanwhile, deaths were also notably down, from 1.4 per million people to to less than 0.4 per million as of Monday, the same data set shows.

Now, as Omicron spreads fast, far, and wide, South Korea will no longer use GPS monitoring to enforce quarantines and will also end daily checkup calls to low-risk coronavirus patients as a fast-developing Omicron surge overwhelms health and government workers.

The speed of transmissions has made it impossible to maintain a tight and proactive medical response, Jeong Eun-kyeong, the country's top infectious disease expert, said Monday.

9-fold increase in new cases

The Korea Disease Control and Prevention Agency (KDCPA) reported 38,691 new cases of the virus, a nine-fold increase from the levels seen in mid-January, when omicron became the country's dominant strain. Jeong said the country may see daily jumps of 130,000 or 170,000 by late February.

South Korea had been seen as a success story during the earlier part of the pandemic after it contained infections and hospitalizations more effectively than most countries in the West.

Health authorities worked closely with biotech companies to ramp up laboratory tests and aggressively mobilized technological tools and public workers to trace contacts and enforce quarantines.

The country's strengths have been rendered irrelevant by the unprecedented spike in infections fueled by the omicron variant, which has stretched health and administrative resources.

At home treatments

Officials had already been forced to expand at-home treatments, reduce quarantine periods, and reshape testing policy around rapid antigen test kits, despite concerns over their reliability, to save laboratory tests for people in their 60s or older and those with existing medical conditions who are at higher risk for serious illness.

The plans to further ease the monitoring and quarantines came as health and public workers struggle to keep up with the near 150,000 people being treated at home for mild or moderate symptoms, which have led to delays in drug prescriptions and has paralyzed contact tracing.

Officials say public workers who had been monitoring virus carriers through GPS-enabled smartphone apps will now be assigned to help with at-home treatments. Virus carriers will no longer be required to report to local health offices when they leave home to visit doctors, while their cohabiting family members can now freely go out to buy food, medicine and other essentials.

Low-risk virus carriers, who are in their 50s or younger and have no pre-existing medical conditions, will now be left to monitor their conditions on their own and contact local hospitals if their symptoms worsen. Health workers will still make daily checkup calls to people in their 60s and older or those with pre-existing medical conditions.

Transition

While omicron is spreading much faster than previous versions of the virus, the rates of hospitalization and death have so far been lower than cases linked to delta, which drove a devastating surge in December and early January.

The KDCA said 270 patients were in serious or critical conditions as of Monday, while less than 46% of the country's intensive care units designated for COVID-19 treatment were occupied. Experts say the country's rapidly growing caseload is likely to drive up hospitalisations in coming weeks.

"We are planning to transition toward an anti-virus strategy that's concentrated on maintaining essential social functions while dealing with huge numbers of infections and people placed under quarantine," Jeong, the KDCA's commissioner, said during a government briefing.
