VARREDURA ESPACIAL PARA IDENTIFICAÇÃO DE ÁREAS DE RISCO EPIDÊMICO E FATORES ASSOCIADOS A DENGUE: EXPERIÊNCIA EM BELO HORIZONTE, MINAS GERAIS

Abstract

Objective: To present spatial scanning as an instrument to identify clusters of dengue and factors associated with epidemics in Belo Horizonte / MG. Methods: Ecological study, with dengue cases notified between 2007 and 2010. For the identification of clusters, the spatial scanning statistic Scan was used. Logistic regression investigated the association between clusters and the building infestation index (IIP), proportion of verticalized buildings (PIV), Recebido em: 11/09/2020 Aceito para publicação em: 21/01/2021.

Results: There were 76,592 dengue cases and five clusters were identified per period: in 2007/2008 the aggregates concentrated 30% of the population and 67% of the cases; 2008/2009 grouped 13% of the population and 60% of cases and in 2009/2010 concentrated 34% of the population and 62% of cases. There was an association with PII in 2007/2008 (OR = 5.0; p <0.01) and high OD in 2008/2009 (OR = 8.4; p = 0.01) and 2009/2010 (OR = 9,5; p <0.01). Conclusion: Spatial scanning can be useful to strengthen territorialized surveillance of dengue by allowing identification of priority areas for effective disease control. Keyword: Dengue.
