TRUMP got #COVID19 despite using frequent rapid tests.

Does this mean frequent rapid tests failed?

No! To stop outbreaks we must stop onward spread. The frequent tests worked! Now, Trump will not spread to others. The transmission chain is severed. This is public health.

Tests are not prophylactics. They alone cannot stop the test taker from getting infected. But can serve to stop onward spread from the tester. The goal is to sever enough transmission that R<<1/outbreaks die out.

To stop from getting infected, masks/social distancing are needed
People are suggesting this is a failure - on the contrary this is demonstrating, in real time, how frequent rapid tests can work. Detecting trump early in his infection means we are removing days of him potentially spreading to others and spawning tens or hundreds of new cases.
