Perhaps we should start with the name. Spain was neutral during the First World War; its press was uncensored. So when a wave of influenza hit the Iberian peninsula in May, 1918, it made the papers. The disease had been tearing through Allied troops on the Western Front for several weeks, and the first registered case had been two months earlier, in a military camp in Kansas, USA. But this information was not in the public domain. The authorities of the warring nations felt that letting their citizens know it was not only the enemy attacking their troops would be bad for morale.

西班牙流感-第一名骑兵

也许我们应该从名字开始。第一次世界大战期间，西班牙是中立的；它的新闻未经审查。因此，当1918年5月一波流感袭击伊比利亚半岛时，便发表了论文。这种疾病已经在西线的盟军中流传了几周，第一例登记的病例是两个月前，在美国堪萨斯州的一个军营中。但是，此信息不在公共领域。交战国家的当局感到，让本国公民知道，不仅敌人进攻他们的部队会对士气产生不利影响。
