In addition, this study also contains the content that it is difficult to prevent delta mutations with rapid transmission power with the current quarantine system centered on diagnostic tests. There is a high chance that a confirmed person will infect others before going into self-quarantine.



If so, what are the alternatives, followed by Cho Dong-chan, an exclusive medical reporter.



<Reporter> The



reason for the rapid increase in the number of patients with severe cases in recent years is group infections in nursing homes.



In August and September, the number of confirmed cases was about 20 and around 400, and in October, 63 cases and 1,733 people were confirmed.



Since residents of nursing hospitals and facilities stay only in hospitals, they view the source of infection as medical personnel and workers, and have them undergo PCR testing twice a week.



National Medical Center analysis data.



Delta mutation, which accounts for nearly 100% of domestic infections, is contagious for eight days from 3 days before symptoms such as fever and cough to 5 days after symptom onset.



However, on average, the quarantine time for confirmed patients was 4 days after symptom onset.



Controlling only one out of the eight days that you can infect others.



Although it is difficult to diagnose in the asymptomatic stage, it is important to diagnose it immediately after symptoms.



This is because infectivity is strongest on the first day after symptom onset.



Although it is the most accurate, the current PCR test, which takes an average of two days, should not be insisted on, but rapid PCR or rapid antigen test that can be diagnosed within an hour or two should be actively used.



Rapid PCR tests are as accurate as current PCRs.



[Bang Bang-hwan/National Medical Center New Infectious Diseases Central Clinical Committee: Rapid PCR is a very good test with almost the same level of reliability as our normal PCR, but it is expensive and there are many hospitals that do not have insurance and do not have this kit. .]



Rapid antigen test is known to have low accuracy, but it depends on how it is used.



[Bang Bang-hwan / Central Clinical Committee for Emerging Infectious Diseases, National Medical Center: Confirm that the PCR was negative within the last 2-3 days when admitted to the hospital.

2 to be higher a rapid antigen test, in fact, rapid antigen test is more reliable one on the verge of hospitalization one to the PCR yirang admitted shortly before that three days ago.]



For this reason, even the British Department of Health and the US Centers for Disease Control and Prevention's a quick test often It is said to help prevent infection.
