Schools are not obligated to share any information related to positive tests except to those directly impacted. Some do anyway, but my understanding is many stopped rather quickly because the community created more hassle than it was worth when those communications were sent out. Basically, enough people effectively weaponized the schools transparency.I highly doubt it given what a political football it is. My four year old's preschool had two cases of it passed between students but they ONLY know that because the two families are friends and are pretty isolationist. They basically "confessed" it on the facebook page in the interest of full disclosure.
Concerning contact tracing, this is going to sound more cold than intended because I don't think it's their fault - but our experience with reporting agencies has been they don't care about that information. The manner in which they're operating is to put out the fire then move onto the next one. They're not devoting resources to cohesively assembling the data - and I don't blame them. Of course the information is documented, but not in any manner in which it could be easily analyzed. Because like you said their objective is to figure out where a case likely stemmed from, not where it actually came from. So they identify those that were in contact with the subject during the incubation period, give quarantine orders, then stamp the case closed and move onto the next one.
