In Canada, they do 1 better. If you have contact with someone who has the CCP virus or enter Canada, when they force you to get the test and the results are negative, they still make you quarantine for 2 weeks even if you have no symptoms. Begs the question: Why do they even bother to make you get the test if they don't believe the results? My guess is there are 2 main reasons:

1. Government showing the lowly peasants that they're in charge and can do what they want.

2. The only type of test they accept in Canada (the PCR) has a relatively high false positive rate. So if you test enough people, even if there was no virus at all, it will still appear like there is a virus outbreak from just the false positives.
