Well we have to be smart about evacuations and things like that.
IMO, college campuses are one of the most obvious breeding grounds. As it is, statistics show that the rates of acquiring meningitis are 6x the normal rate in college housing. If there is an outbreak, this is going to be a big problem for two reasons. First, because there is a large enough population which helps the spread. Second, because young people are generally healthier, it's likely that the more resistant/dangerous strains will take hold here than say, in a nursing home where you will have large numbers succumbing anyway.
IMO, this is what you shut down right off the bat at the outbreak of a pandemic.
