<Reporter> The

government said it is conducting a 'population immunity' survey to find out how much of the domestic population has corona19 immunity.

The 'National Health and Nutrition Survey' is conducted for about 10,000 people each year. The blood samples obtained at this time are agreed to be used for corona19 immunity surveys with the consent of the parties.

[Kwon Joon-wook / Deputy Head of Central Defense Countermeasures Division: The National Health and Nutrition Examination Survey has already begun and some blood samples have begun to be obtained.]

In the case of Corona 19, more than 60% of the general population has antibodies It is known that the virus is no longer spreading rapidly because 'group immunity' is formed in the society.

Therefore, the results of the survey are used to establish long-term measures for prevention.

The quarantine authorities are also considering ways to conduct antibody tests preferentially in Daegu and Gyeongbuk areas where a large number of patients have occurred.

As a method of investigating the presence or absence of antibodies, we are considering the rapid diagnostic kit and the enzyme immunity detection method used in the laboratory.
