You asked me why I was doubting what Disney was saying about transmission of the virus in the parks. I asked you what they’re saying. Have you seen any statements from Disney about exposure or infection in the parks?
There are certainly challenges to contact tracing—especially in populations that aren’t taking recommended precautions. If contact tracing is indeed being done (and there’s
reason to doubt that it is), then someone would have a pretty good idea if Disney CMs are at greater, less, or about the same risk as anyone else. I would only hope that the someone would notify CMs (and their union representatives).
Contact tracing among guests would be even more difficult, though not impossible if Disney had any interest in helping. Magic Bands could be used to do this, as could the MDE app on mobile phones. It is very challenging (and costly and time consuming!) to keep people safe and informed during an outbreak of infectious disease. This is why most entertainment venues are closed.
I have a problem with those who (disingenuously) say, “Disney has proven that it’s possible to safely reopen!” when we don’t actually know how safe it is. I also have a problem with an uninformed public, who don’t have the information they need to know whether a trip to WDW puts them at greater risk, less risk, or about the same amount of risk as a trip to the grocery store. Many have said that the mask policy and plexiglass dividers have made them feel safe (“safer at Disney than anywhere else!”), but we just don’t know.
