Probably if we had any significant spread at all, we’d immediately stop and what we’d try to do is to track and determine where they’re coming from and whether there had been a spread on campus. I would say, ultimately, we would cease completely if we saw that this was spreading around the campus and something more than an isolated case was happening.”
