Ahn Cheol-soo, Chairman of the South Korea Presidential Transition Committee, on Wednesday said the government would conduct COVID-19 antibody testing on 10,000 people.

According to the chairman of the presidential transition committee, this will determine how many of them have antibodies and learn more about immunity.

The transition committee requested the government conduct the testing because it will provide “very helpful scientific data for disease control and containment management,’’ Ahn said.

An antibody test shows whether people were infected with the virus in the past, even if they were asymptomatic.

Ahn said antibody testing for a large number of people became more important in the COVID-19 wave driven by the highly transmissible omicron variant.

Daily COVID-19 cases rose above 420,000 on Wednesday amid concerns over the continued rise in seriously ill patients and deaths over the fast spread of the “stealth omicron’’ subvariant.

Ahn said the transition committee had asked the government to draw up measures to reduce the number of seriously ill patients and deaths.

President-elect Yoon Suk-yeol has asked his transition committee to put its top priority on overcoming the COVID-19 crisis, including compensation for small businesses hit by the pandemic.
