“… In every case the first assumption is that the pandemic spatial diffusion is not randomly determined. The basic principles of epidemiology are that three global Determinants are required for an epidemic (or pandemic) to occur (Desenclos and de Valk, 2005 ; Che, 2019 ): the new or existing Pathogen attain characteristics able to trigger its exponential replication; the Host presents suitable characteristics and favorable behaviors apt to sustain the replication of the pathogen; the Environment (sensu Eisenberg et al, 2007 ) guarantees prolonged idoneous conditions for the spreading of the pathogen. Secondarily, in most cases a geography-based method is applied with the general purpose to produce a map or a spatially-based statistic output and the specific purpose to generate new information.…”

“…Pandemics are multifactorial events with complex origin (Che, 2019 ), and many of their contributing determinants, both fostering or hampering the infection, are not well-known, or even unknown (Tscherne and García-sastre, 2011 ). Territory represents the logical framework where epidemiological determinants’ influence can be traced (Eisenberg et al, 2007 ), but also, pragmatically, the field where their assessment becomes partially possible (Kundi, 2006 ).…”

The present work aims to give an overview on the international scientific papers related to the territorial spreading of SARS-CoV-2, with a specific focus upon applied quantitative geography and territorial analysis, to define a general structure for epidemiological geography research. The target publications were based on GIS spatial analysis, both in the sense of topological analysis and descriptive statistics or lato sensu geographical approaches. The first basic purpose was to organize and enhance the vast knowledge developments generated hitherto by the first pandemic that was studied “on-the-fly” all over the world. The consequent target was to investigate to what extent researchers in geography were able to draw scientifically consistent conclusions about the pandemic evolution, as well as whether wider generalizations could be reasonably claimed. This implied an analysis and a comparison of their findings. Finally, we tested what geographic approaches can say about the pandemic and whether a reliable spatial analysis routine for mapping infectious diseases could be extrapolated. We selected papers proposed for publication during 2020 and 209 articles complied with our parameters of query. The articles were divided in seven categories to enhance existing commonalities. In some cases, converging conclusions were extracted, and generalizations were derived. In other cases, contrasting or inconsistent findings were found, and possible explanations were provided. From the results of our survey, we extrapolated a routine for the production of epidemiological geography analyses, we highlighted the different steps of investigation that were attained, and we underlined the most critical nodes of the methodology. Our findings may help to point out what are the most critical conceptual challenges of epidemiological mapping, and where it might improve to engender informed conclusions and aware outcomes.

“…Ce qui fait la spécificité des virus, c'est leur fonctionnement de parasite génétique qui implique à la fois la nécessité de survivre assez longtemps dans les cellules de l'hôte pour s'y répliquer et donc se transmettre et une capacité de mutation pour se protéger des phénomènes de mémoire immunologique. Cela conduit à une sélection naturelle des formes les plus contagieuses et suffisamment virulentes pour que l'épidémie se propage [4,5].…”
