The Korean Centers for Disease Control and Prevention (KCDC) announced on the 14th that only one (0.07%) was found to have the antibody as a result of coronavirus antibody tests in the blood of 1,440 people. This is the second antibody test result after the first national survey that announced that only 1 in 3,055 people (0.03%) had antibodies on July 9.
At the time of the announcement of the results of the first test, there was a controversy that “the test was insufficient because some areas such as Daegu where a large-scale coronavirus infection occurred were not included”, but this time the area was included of Daegu. However, the antibody retention rate did not reach 0.1%. Consequently, there is an assessment in the medical community that “the proportion of new confirmed cases that have not identified the route of infection for the fifth time is greater than 20%, and the fact that there are few occult infections does not coincide”. Antibody testing is a testing method that checks how many ‘hidden infected people’ have passed without any other suspicious corona symptoms and without a diagnostic test.
This secondary antibody test is the result of collecting 1,440 serum cases from people who participated in the National Health and Nutrition Survey in 13 cities and provinces, including Daegu, Daejeon, and Sejong from June 10 to last month. . The domestic antibody retention rate was again lower than in New York (24.7%) in the US, London (17%) in the UK, Wuhan (3.2%) in China and Tokyo ( 0.1%) in Japan.
“At the expert advice meeting on days 2 and 9, it was noted that he limited himself to explaining the epidemic situation after mid-August because the sample collection period for the second investigation was before the 14th of last month “said Eun-kyung Chung, director of the Korea Centers for Disease Control and Prevention. The fact that the positive rate was lower compared to the case was the effect of the few confirmed cases from June to the beginning of August ”.
“Thanks to the ‘3T’ strategy of the quarantine authorities, such as testing, tracing and treatment, there are not many people who go through without knowing if they have corona,” said Um Joong-sik, professor of infectious medicine at Gil de la Hospital. Gachon University. said. However, among experts in the field of infectious sciences, there is also an assessment that “the exact situation can only be understood by testing at least 10,000 or more people” and “because only 1 antibody is positive, care is taken to give statistical significance. “
The Korean Centers for Disease Control and Prevention (KCDC) announced on the day that “in the future, we will continue to investigate additional antibodies targeting 10,000 military personnel and 10,000 regional sample groups.”
