I'm skeptical of the efficacy of testing. Say you get tested, then on the way out of the clinic or on your way home you pick up the virus. A day or so later, however long the test results take you are notified that you are negative so you go out and interact with others except you are not actually negative because you picked up the virus after being tested and now you have a false sense of security from the negative test. Perhaps I'm overlooking something though.
In Finland, the problem is that lack of testing hides the problem.
The same kind of problem occurred over a decade ago, when certain older lady politicians get fed up with street prostitution. Certain laws were put in place, and now there is very little street prostitution in Helsinki. What you do have, however, is lots more human trafficing, especially for prostitution; slavery and so on.
But, since it is hidden, and not in-your-face, these older lady politicians are happy and not annoyed anymore, so they consider it a very good win.
See? It is not to help people feel safe, but to realize they are not; that they can be virus spreaders even if they feel perfectly healthy.
It is a completely different thing for even a respected doctor to say that although Finland is supposed to only have 400 cases, the true number is likely an order of magnitude higher,
and actually having those bigger numbers from testing, when the problem is that most people don't think the situation is serious enough
for them to behave any different.
