Abstract：
In Alaska, the 1918-20 influenza pandemic was devastating, with mortality rates up to 90% of the population, while in other arctic regions in northern Sweden and Norway mortality was considerably lower. We investigated the timing and age-patterns in excess mortality in Greenland during the period 1918-21 and compare these to other epidemics and the 1889-92 pandemic. We accessed the Greenlandic National Archives and transcribed all deaths from 1880 to 1921 by age, geography, and cause of death. We estimated monthly excess mortality and studied the spatial-temporal patterns of the pandemics and compared them to other mortality crises in the 40-year period. The 1918-21 influenza pandemic arrived in Greenland in the summer of 1919, one year delayed due to ship traffic interruptions during the winter months. We found that 5.2% of the Greenland population died of the pandemic with substantial variability between counties (range, 0.1% to 11%). We did not see the typical pandemic age-pattern of high young-adult mortality, possibly due to high baseline mortality in this age-group or remoteness. However, despite substantial mortality, the mortality impact was not standing out relative to other mortality crises, or of similar devastation reported in Alaskan populations.
摘要：
在阿拉斯加,1918-20年的流感大流行是毁灭性的，死亡率高达90%的人口，而在瑞典北部和挪威的其他北极地区，死亡率相当低。我们调查了格陵兰在1918-21年期间超额死亡率的时间和年龄模式，并将其与其他流行病和1889-92年的大流行进行了比较。我们访问了格陵兰国家档案馆，并按年龄转录了1880年至1921年的所有死亡病例，地理,和死因。我们估计了每月的超额死亡率，并研究了大流行的时空模式，并将其与40年期间的其他死亡率危机进行了比较。1918-21年的流感大流行于1919年夏天抵达格陵兰，由于冬季的船舶交通中断而推迟了一年。我们发现，格陵兰人口中有5.2％死于大流行，各县之间存在很大差异（范围，0.1%至11%）。我们没有看到年轻人死亡率高的典型大流行年龄模式，可能是由于该年龄组或偏远的基线死亡率高。然而,尽管死亡率很高，相对于其他死亡危机，死亡率影响并不突出，或在阿拉斯加人口中报告的类似破坏。
