BACKGROUND
The last outbreak of yellow fever in the city of Barcelona, Spain, was caused by a ship arriving from Cuba. The objective of this study was to describe and analyze the epidemic of 1870 by using the available mortality data.
METHODS
The information on 1,235 deaths identified in the parochial registries was analyzed, using statistical and epidemiological procedures for epidemic outbreaks.
RESULTS
Mortality due to yellow fever was 549.7 per 100,000 inhabitants. The temporal distribution of the deaths showed two peaks at the end of September and October with the last fatalities occurring in December 1870. The distribution of the fatalities in the city's neighborhoods was unequal. In La Barceloneta, in particular, more fatalities were found in the streets adjacent to the port than in the most remote streets (r=0.83; p<0.0001).
CONCLUSIONS
This study reveals a temporal bimodal mortality distribution for yellow fever during the outbreak, with a high impact in adult men and in the La Barceloneta neighborhood.
背景
西班牙巴塞罗那市上一次黄热病疫情是由一艘来自古巴的船只引发的。本研究的目的是利用现有的死亡率数据描述和分析1870年的疫情。
方法
分析了教区登记处记录的1235例死亡信息，采用统计和流行病学方法对疫情爆发情况进行分析。
结果
黄热病导致的死亡率为每10万居民549.7人。死亡的时间分布在9月底和10月出现两个高峰，最后一例死亡发生在1870年12月。城市各街区的死亡分布不均。特别是在巴塞罗那内塔区，港口附近街道的死亡人数比最偏远街道的死亡人数更多（r=0.83；p<0.0001）。
结论
本研究揭示了疫情期间黄热病死亡时间呈双峰分布，对成年男性和巴塞罗那内塔区影响较大。
