I'd also note, and I think that this is important for people to understand, it is not necessarily the locations but the people who were at the locations at the time of potential exposure that is the important part. So the fact that things may have happened at those locations—people may have been at those locations, say, this morning, for example, before they were notified—that in itself does not necessarily increase the risk. The risk existed when people were there at the same time as the case was there.
