Absolutely, it's exactly as you said. It's an old Soviet/hammer method, I agree. But how many PCR tests have we had? Maybe we in the government have them more often because we are exposed to many international meetings. But the ordinary citizen may have one or two PCR tests in a year. With the antigen test, you can ascertain your infectious status every week—twice a week. And this is the problem with SARS-CoV-2, because a large portion of the population is fully asymptomatic. These people would never know they are infectious. By taking the antigen test once or twice a week, I can search my infectious disease. I can find out if I am positive or not. If I'm positive, I can isolate myself much earlier to prevent new generations or propagation lines of the virus, and if I am negative, I can go to work and can send my children to school.
