Is this a more effective way to stop the spread of the corona virus?

 I put forward this suggestion on a more effective way to control the spread of the virus.

We should get away from the wasteful activities (such as contact tracing and safe entry recording) and focus on dealing with the symptomatic cases in a more effective manner.

Please help me to test this hypothesis by providing research information.
