Urban, Architectural, and Socioeconomic Factors Contributing to the Concentration of Potential Arbovirus Vectors and Arbovirosis in Urban Environments from a One Health Perspective: A Systematic Review

Today, urbanisation and environmental changes are increasingly influencing the social and biological landscape of our planet. This systematic review aims to assess the relationship between urban–architectural and socioeconomic factors and vector concentrations in the urban environment. Following the Preferred Reporting Methodology for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, the PubMed, Scopus, and Cochrane libraries were screened for studies conducted in urban contexts and those involving only arboviruses and potential exposure to arboviral vectors in urban environments, published from the beginning to 22 April 2025. Out of a total of 171 identified studies, 132 were selected for further analysis. Of these, 14 studies were eligible. The included studies reported different ways of measuring vector density and different considerations of the urban–architectural or socio-demographic factors related to it. The studies were set in different urban contexts: Asia, Central and South America, Africa and Oceania. Among the vector species, Aedes aegypti was the most analysed, often with Aedes albopictus . Socioeconomic status emerges as a determining factor. Low-income areas experience higher mosquito densities due to overcrowding, sub-optimal infrastructure, and environmental neglect. This review highlights the importance of implementing a standardised and effective global approach in urban health planning.
