Mar 1918–Jul 1920 Flu pandemic in Europe▲
In 1918, cases of a new virulent strain of influenza started appearing on the European military fronts, in particular around the major troop staging and hospital camp in Étaples, France. Because news from the front was censored, the first big public outbreak was in neutral Spain, after which the Allies called it 'Spanish flu' - although whether it originated in Europe, North America, or China remains uncertain. The flu killed more than 400,000 in France, over 500,000 in Italy, about 260,000 in Spain, 250,000 in Britain, and 150,000 in Germany, with some 2.6 million deaths in Europe overall.
