I focused on the fact that border closures put every country at greater risk. If medical personnel believed they would not be able to travel home after working in an Ebola-affected country, they would be less likely to volunteer to help. This would reduce the likelihood that Ebola would be controlled, in turn increasing the chances that the disease would spread to the very countries whose leaders were trying to keep their people safe. Like so many twenty-first-century challenges, Ebola was not a zero-sum fight in which some countries could “win” by pursuing their interests in a vacuum.
