摘要

2006年2月至4月,毛里求斯岛受到基孔肯雅热大规模流行暴发的影响。据观察,这一流行病与毛里求斯2006年3月至5月期间的高死亡率有关。本研究的目的是分析超额死亡率的性别和年龄组分布。2000年至2006年的人口和死亡率数据来自毛里求斯中央统计局。计算了2006年每月超额死亡率,并分析了按性别和年龄组划分的超额死亡率分布。在≥50岁年龄组中,男女加起来的超额死亡率为91.5%。在≥50岁年龄组,男性总超额死亡率(EDR)比女性总超额死亡率高出66%。我们的研究结果表明,CHIKF与死亡率增加有关,特别是在≥50岁年龄组,男性比女性更容易死亡。虽然在其他研究中也有与CHIKF相关的死亡报告,但以前没有描述过CHIKF暴发期间高死亡率的概况。

An analysis of the excess mortality profile during the 2006 Chikungunya Fever epidemic in Mauritius
The Island of Mauritius was affected by a large scale epidemic outbreak of Chikungunya Fever (CHIKF) from February to April 2006. It was observed that this epidemic was associated with an excess mortality during the months of March to May 2006 in Mauritius. This study was aimed to analyze the gender and age group distribution of the excess mortality. Population and mortality data were obtained from the Mauritius Central Statistics Office for the years 2000 to 2006. The excess monthly mortality was computed for 2006 and the distribution of excess mortality according to gender and age groups was analyzed. For both genders combined, the excess mortality was 91.5% in the age group ≥ 50 years. For the ≥ 50-year age group, the total male excess death rate (EDR) exceeded the total female EDR by 66%. Our results indicate that CHIKF is associated with an increased mortality particularly in the ≥ 50-year age group with males being more vulnerable than females to mortality. Although there have been reports of CHIKF related deaths in other studies, the profile of the excess mortality during a CHIKF outbreak has not been previously described.
