The Ebola episode holds further lessons. One reason that the disease spread so rapidly in Liberia and Sierra Leone is that both are war-ravaged countries, where a large proportion of the population is malnourished and the health-care system has been devastated.
埃博拉危机的教训不仅于此。埃博拉在利比里亚和塞拉利昂传播得如此迅速，一个原因是这两个国家都饱受战争蹂躏，很大一部分人口营养不良，医疗体系也被摧毁殆尽。
