在温带地区,流感疫情每年在冬季发生一次。人们对不同地点的流行病之间的相似性知之甚少。我们分析了1972年至1997年美国、法国和澳大利亚的肺炎和流感死亡人数,以检验这三个国家在空间和时间上的相关性。我们发现法国和美国在这两个领域都有很高的相关性(在影响方面的相关性,斯皮尔曼的ρ=0.76p<0.001,以及在流行病发生时间的同步性测试,p<0.001)。当考虑到与美国或法国相比,澳大利亚流感疫情系统性提前或推迟半年时,我们没有发现美国和澳大利亚之间或法国和澳大利亚之间存在类似的相关性。这些结果支持在半球水平上的高度相关性,并表明全球流行病的半球间循环遵循一条在领先半球反复变化的不规则路径。
Influenza epidemics occur once a year during the winter in temperate areas. Little is known about the similarities between epidemics at different locations. We have analyzed pneumonia and influenza deaths from 1972 to 1997 in the United States, France, and Australia to examine the correlation over space and time between the three countries. We found a high correlation in both areas between France and the United States (correlation in impact, Spearman’s ρ = 0.76, p < 0.001, and test for synchrony in timing of epidemics, p < 0.001). We did not find a similar correlation between the United States and Australia or between France and Australia, when considering a systematic half-year lead or delay of influenza epidemics in Australia as compared with those in the United States or France. These results support a high correlation at the hemisphere level and suggest that the global interhemispheric circulation of epidemics follows an irregular pathway with recurrent changes in the leading hemisphere.
