That said, there is obviously a weakspot in ND's protocols. Contact tracing should reveal what that weakspot is.
Hopefully, this will be an opportunity to learn what happened, and get it fixed to ensure it doesn't happen again. Hopefully we hear from Kelly that they've identified some things (without specifics) they will do differently moving forward.
The team and program have all been very diligent so I doubt anybody did anything "wrong". It's a unique situation and we are all still learning as we go.
