" But the truth about quarantines was that you could never catch everyone in your net, not even if you tagged and tracked every person who’d come in contact with the Typhoid Mary. And in this case, there didn’t seem to be a Typhoid Mary. Instead, pockets of sickness had just bloomed up like hideous flowers in several places at once, and then spread so fast that tracing the vectors was something like impossible. And “the government”—well, Red had zero confidence that the government would be able to do anything. Not because it was full of bad people or there was a giant conspiracy or anything like that. "
