S.Korea widens public access to virus self-test kits amid surge

The decision comes as South Korea grapples with a nationwide rise in cluster infections, spurring authorities to urge tougher enforcement of distancing rules to avert a fourth wave of the pandemic.

The makers of the kits, SD Biosensor Inc and Humasis Co Ltd , were given three months to provide further clinical trial data on self-testing as a condition of the approval, the drug safety ministry said in a statement.

Although the products have been available in European countries since last year, South Korea had limited their use to medical specialists.

The kits could yield results within about 15 minutes, but with an accuracy of 90%, the ministry added, versus the 98% proven for industry-standard PCR tests and specialist-administered rapid tests.

"Despite the differences in accuracy, there is a need to use those kits as a supplementary tool," Acting Prime Minister Hong Nam-ki told a daily meeting on virus fighting efforts.

"If PCR tests offer microscopic examinations with almost 100% accuracy, self-test kits can be compared to results made with naked eyes."

Health authorities have warned that the kits have a greater possibility of false negatives if handled by non-professionals, since a high viral load in the nasal passageways is often essential for a reliable result.

But officials have expressed positive views in recent weeks about allowing limited use, amid fears of a potential fourth wave.

Some local government chiefs have urged their use in homes, restaurants, shops and places of worship as a quick and easy way to detect possible infections.

Thursday's 797 new infections reported by the Korea Disease Control and Prevention Agency were the highest since Jan. 7, when the third wave began to abate after the daily figure topped 1,200 in late December.

The nationwide tally stands at 117,458 infections, with 1,811 deaths.
