This week, Ebola arrived in New York City -- America's most crowded and most media-saturated metropolis. So, as word spread on Thursday, so did the hysteria. But thankfully, Ebola (or "Ebowla," as some christened it in honor of the infected doctor's sporting foray the night before his symptoms appeared) remains much harder to spread than rumor and misinformation. As threats go, Americans have a greater chance of dying from a bee sting than catching Ebola. Meanwhile, Canadians are dealing with this week's deadly shooting in Ottawa. The media response there stood in stark contrast to ours. Any changes, The Globe and Mail wrote, should not be "as a panicky reaction to a very small number of men" who "are not an existential threat." We could learn much from our northern neighbors. As we heed NY Mayor de Blasio's warning to stay calm, we should also remember Montaigne, who said, "There were many terrible things in my life, but most of them never happened."
