In my province contact tracing has gotten completely overwhelmed and has basically been rendered useless. There is a lot of suspicion and concern that schools are driving our spread, good reason to believe it, but no hard evidence provided by contact tracing.
Saying this not to go OT and discuss that, but to illustrate why I think it will be quite difficult for any outbreak to be pinned on WDW when I would have to assume much of the people who go there are also going various other places, traveling to get there, contact tracing isn’t happening, etc.
