With more than ten thousand COVID-19 cases in Korea, just 74 days after the first case, the pandemic has resulted in huge social costs. To alleviate some of those costs, there have been calls for the disclosure and verification of the performance of what is known as primer, a core substance for amplifying genes to diagnose the coronavirus.

After a specimen is taken from a person's mouth, a certain part of the viral genes is amplified. Primers, a short nucleic acid sequence that attaches to certain viruses, play a key role in diagnosing the virus. When a virus is detected through gene amplification, a fluorescent substance appears to show if the test is positive or negative. The primer, used to detect COVID-19 cases in Korea, has been developed recently by the Institute for Basic Science. It enables to see test results in just four hours. The institute disclosed the nucleic sequence of the primer and the results of its research to the Korea Society for Brain and Neural Science. The institute is receiving many inquiries from overseas as its primer allows even ordinary research facilities to easily detect COVID-19 in asymptomatic people.
[Soundbite] WON JONG-HA(INSTITUTE FOR BASIC SCIENCE) : "We conducted this research because asymptomatic people and those who have met people with symptoms or have been near them cannot undergo tests in hospitals and must pay a lot for testing."
The disclosure of the primer used in diagnostic kits is expected to help reduce social costs. However, in Korea the performance of primers and their evaluation data are not disclosed properly because they are regarded as businesses' intellectual property.
[Soundbite] SEO SANG-HEE(PROF., CHUNGNAM NATIONAL UNIVERSITY) : "Things that involve public taxes must be disclosed and verified transparently to help minimize false positives. The public must know the nucleic sequence of the primer used in testing."
Experts point out that primers and their performance evaluatio
