Only variables below the selected threshold are presented. D2: explained deviance.
DUF: discontinuous urban fabrics (between 30 to 80% of the total surface is impermeable, covered by buildings, roads and artificially surfaced areas); EDP: earliest date of presence of an imported case during viremia in the study area; GDD: bounded growing degree days; NDVI: normalized difference vegetation index.
(1) The different variables are classified as follows. LC: variable related to land cover. S: variable related to surveillance and control. SE: socioeconomic variable. M: meteorological variable. RD: reporting delay (in days), as the period between the earliest date of presence of an imported case and the date of case reporting.
