Per capita income, population volume and density, the structure of cities, transport infrastructure or whether districts have their own schools are all factors that can affect the spread of COVID-19. This has been confirmed by a study carried out in 73 districts in Barcelona by researchers from the departments of Geography and Economics of the Universitat Rovira i Virgili, the results of which have been published in the Journal of Public Health. The research reveals that the analysis of the characteristics of every district can facilitate decisions on the specific measures to be applied to individual districts in an attempt to effectively reduce the rate of infection.
