Very few Pacific islands escaped the 1918-1919 influenza pandemic. Subsequent influenza epidemics in the established colonial outposts of American Samoa and New Caledonia infected many but killed very few persons whereas the extraordinarily isolated Niue, Rotuma, Jaliut and Yule islands experienced high mortality influenza epidemics (>3% of population) following 1918. These dichotomous outcomes indicate that previous influenza exposure and degree of epidemiological isolation were important mortality risk factors during influenza epidemics on Pacific islands.
在 1918-1919 年流感大流行中，几乎没有太平洋岛屿幸免于难。随后，在美属萨摩亚和新喀里多尼亚等已建立的殖民地前哨，流感在许多人中传播，但很少有人因此死亡，而在异常孤立的纽埃、拉罗汤加、雅利乌和尤利等岛屿，在 1918 年之后经历了高死亡率的流感疫情（>3%的人口）。这些截然相反的结果表明，在太平洋岛屿的流感疫情中，先前的流感暴露和流行病学隔离程度是重要的死亡风险因素。
