Abstract

CANELA SOLER, Jaume et al. A mortality study of the last outbreak of yellow fever in Barcelona City (Spain) in 1870. Gac Sanit [online]. 2009, vol.23, n.4, pp.295-299. ISSN 0213-9111.

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.
