As I responded to the sibling comment, I don't think that is accurate. Of course many, if not most cases can not be traced, many certainly can be. Some people know exactly where they got covid, and who they exposed, and where.

The US has 50,000 full time contact tracers working to collect this information. Surely there is some data by now?

>Your questions are unanswerable.

IF the question is categorically unanswerable (which I don't believe), contact tracing programs should be disbanded.

Contract tracing != "gathering evidence of transmission in any particular location/context."

Instead, please think of it as "one of the most powerful, non-medicinal, mechanisms for interrupting disease transmission."

It accomplishes this through its overt actions: attempting to alter the behavior of potential and exposed contacts by encouraging quarantining for an appropriate length of time and to get tested if symptoms develop.

I disagree. Understanding how and where COVID spreads has been an essential part of contract tracing in all of the countries that have successfully implemented it. This data is absolutely collected by tracers.

It’s dangerous to not put much credence in where people think they got the virus. We have all kinds of biases that mean we are not going to be very good at this.
