Antibody testing of judgment materials to unlock lockdown begins at 6:27 on April 15, USA
In the United States, in order to release so-called "lockdowns" such as restrictions on going out, "antibody tests" of residents have begun as one of the factors that determine the time of day.
"Antibody test" is a procedure in which human blood is collected to check for the presence and amount of antibodies to the new coronavirus contained in the blood. You can know if there is.
Performing this test on a large scale can give an estimate of how much of the population has already been infected.
The National Institutes of Health, NIH in the United States, has started a study to estimate the actual number of infected people by conducting antibody tests on approximately 10,000 people in the United States.
In addition, some states and local governments have announced that they will carry out their own antibody tests.
Some politicians and experts argue that the higher the proportion of people with antibodies, the less likely it is that the infection will spread, arguing that it will be a basis for relaxing restrictions on going out.
On the other hand, basic data such as whether once infected, sufficient immunity can be obtained to prevent re-infection, is still insufficient, and how much of the population is immunized to the new coronavirus. We also do not know that if it is prepared, the spread of infection will be less likely to occur.
A WHO = World Health Organization expert also said at a press conference on the 13th, "At this point, it is unknown whether the person who has been infected with the new coronavirus and has recovered has acquired immunity."
In addition, a new type of coronavirus antibody test kit has just been developed and its reliability is unknown, so public health specialists should point out that it should not be easy to judge whether or not to restrict going out based on the results of antibody tests. There are many houses.
