In the aftermath of the Ebola virus epidemic, a vivid lesson in geographical disparities emerged. When cared for in west Africa, an estimated 70·8% of patients with Ebola died.¹ By contrast, only 18·5% of patients managed in the USA or Europe died.² The most determinant factor in outcomes was a function neither of pathogen virulence nor of host susceptibility, but rather of geography.

在埃博拉病毒流行之后，出现了关于地理差异的生动教训。在西非进行护理时，估计有70·8％的埃博拉患者死亡。¹相反，在美国或欧洲，只有18·5％的患者死亡。^2结果的最决定性因素既不是病原体毒力也不是宿主易感性的函数，而是地理因素。
