In 2011 in Seville (Spain), measles outbreak affected 1759 people. It began in the neighbourhood of Santa Isabel (city San Juan de Aznalfarache), where Roma community resides. We described the outbreak epidemiologically and calculated the risk of disease in the population.


Descriptive study of outbreak and cohort study. Exposed population was considered to Barriada resident and not exposed to the rest of the municipality. The data sources were: the Institute of Statistics of Andalusia, the social services of San Juan´s town and the Epidemiological Surveillance System of Andalusia. We described the outbreak and incidences were calculated and Relative Risk. The cases were confirmed by clinical, laboratory and/or epidemiological.


In the neighbourhood the cases were concentrated among the group between 2 and 19 years, while in the rest of the town occurred in children under 2 and over 19 years. The overall incidence of the outbreak was 0,98 per 1.000 inhabitants, 4,94 in San Juan; from 23,15 in the exposed, 2,1 in the unexposed and in the group of 2-19 years 89,58 in the neighbourhood and 5,33 in the rest on the town.


The outbreak affected more children under 20 years old, unvaccinated and residents in the neighborhood Santa Isabel. The risk of falling ill with measles in the neighbourhood was 11 and 17 in the group between 2 and 19 years. We need to develop strategies to reduce health inequalities that accompany some outbreaks.
