Covid-19: South Korea launches self-treatment scheme as Omicron fuels soaring cases

South Korea launched a self-treatment scheme for patients with mild coronavirus symptoms in order to free up medical resources for more serious cases, as new infections hit a fresh high on Thursday due to the fast spreading Omicron variant.

South Korea has largely been a Covid-19 mitigation success story, thanks to aggressive testing and tracing, social distancing and mask wearing.

But as the highly infectious but less deadly Omicron variant began spreading, the government this month started to shift its strategy away from testing and tracing and towards self-monitoring, diagnosis and at-home treatment.

From Thursday, authorities will only provide care to Covid-19 patients aged 60 and older or with underlying conditions, while others monitor themselves and seek medical help from designated clinics if their conditions worsen.

Medical kits including an oxygen saturation measurement device, a thermometer and a fever remedy - previously available to all patients who treat themselves at home - would now be distributed only to priority groups.

Officials have estimated around 13.5 per cent of new cases would be classified as high risk groups.

The government had already scrapped contact tracing and mandatory self isolation reports based on global positioning system technology.

"The previous scheme is no longer realistic in light of our limited resources, and takes massive social and economic costs compared with our medical needs," health ministry spokesman Son Young-rae told a briefing on Wednesday.

"The goal of our new Omicron response system is to minimise serious cases and deaths by focusing on diagnosing and treating high risk groups, and to prevent the saturation and collapse of our medical capacity."

South Korea's daily number of new cases hit another daily record of 54,122 for Wednesday, bringing its total infections to 1,185,361 among its 52 million people, the Korea Disease Control and Prevention Agency (KDCA) said.

About 96 per cent of South Korean adults have been fully vaccinated and almost 65 per cent received a booster shot.
