The spatial analysis was conducted at the neighbourhood level (urban settings). The socioeconomic measures were the median monthly household income (MMHI) for Brazil and the Socio\u2010Economic Strata index (SES) in Colombia.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>There were 281\u00a0426 notified arboviral cases in Fortaleza and 40\u00a0887 in Medellin. We observed greater concentration of dengue among residents of low socioeconomic neighbourhoods in both cities: Relative Concentration Index\u00a0=\u00a0\u22120.12 (95% CI\u00a0=\u00a0\u22120.13, \u22120.10) in Fortaleza and Relative Concentration Index\u00a0=\u00a0\u22120.04 (95% CI\u00a0=\u00a0\u22120.05, \u22120.03) in Medellin. The magnitude of inequalities varied over time across sites and was larger during outbreaks. We identified a non\u2010monotonic association between disease rates and socioeconomic measures, especially for chikungunya, that changed over time. The Relative Concentration Index and Absolute Concentration Index showed few if any inequalities for Zika. The socioeconomic\u2010specific model showed increased disease rates at MMHI below US$400 in Brazil and at SES\u2010index below level four, in Colombia.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>We provide robust quantitative estimates of socioeconomic inequalities in arboviruses for two Latin American cities.
