The Corona 19 test has only been used to diagnose if the person is infected or to see if he or she has been cured and can now be discharged.

It is the first story to test to return to daily life, but what is this in detail, and what can our country also refer to?

In most countries, the Corona19 test is a way to identify the virus itself.

At this time, even if there is no virus, if the amount is very small, it is judged as negative.

However, the number of cases that are re-established after being judged to cure is increasing worldwide.

A Chinese research team recently found a clue to the problem.

About one-third of the 175 people who were judged completely cured were reconfirmed, and when they were discharged, the amount of antibodies in the blood was compared. If the amount of virus is low and the amount of antibody is high, it means that it has not been re-determined.

In the United States, there have been reports of up to 50% of asymptomatic infections. Among them, the US health authorities say that people who already have more than a certain amount of antibodies should do economic activities regardless of whether they are cured.

There are also opinions that domestic airports will use this type of rapid diagnostic kit.

[Hong Ki-jong / Editor of the Korean Society of Vaccine Society: Although there is some possibility of false positives, even so, it is possible to examine and quickly diagnose kits and inform the other country before arrival (you can consider this) ]

However, rapid diagnostic antibody testing is only about 70% accurate, so it is a good idea to carry a virus test together to increase your confidence when establishing diagnostic and discharge criteria.

In addition, there is a need to further clarify the effective amount of corona19 antibody and the duration of the antibody.
