Tick bite risk as a socio-spatial representation between health and landscapes : An exploratory study in the Chaîne des Puys/Combrailles area, France | Tick bite risk as a socio-spatial representation between health and landscapes

The majority of vector-borne diseases in temperate regions of the northern hemisphere are due to mites, mainly ticks. According to Jongejan and Uilenberg (2005), Lyme borreliosis is currently the most common vector-borne disease throughout its range, which appears to be closely related to that of its vector, the tick. However, it appears that knowledge of tick bite risk remains low in the population (Butler et al., 2016) although some results strongly suggest that social and spatial factors are important considerations in designing effective prevention campaigns (Aenishenslin et al., 2015). The spatial dimension of the tick bite risk is therefore major. Nevertheless, the skill of spatial understanding of the risk in the population remains underestimated notably in its link with the perception of the risk landscapes.As part of a multidisciplinary research project associating epidemiology and social sciences, we focused on the sociospatial representations (Dias & Ramadier, 2015) of the public concerning this tick bite risk. We wish validate the risk related to ticks as a social representation in the population and analyze in the structure of this representation, the elements that make sense to the public, especially in relation to the associated landscapes elements (forests, mountains, lakes…).The data collection was done through short personal interviews of about 20 minutes mobilizing "free association" (Rodrigues et al., 2015), and mental maps coupled with textual analysis (Dernat et al., 2016). This technique is particularly suitable for the socio-spatial study of the risk. Indeed, the exploration of categorization processes related to representations of space is necessary to understand the relationship between an environment and social relations (Dias & Ramadier, 2017). More than a hundred people were surveyed during 2018 in several sites of the Massif Central through an epidemiological, geographical and social sampling. This talk aims to present the results of this exploratory study. It will highlight the constitutive elements of the representation by showing their construction network articulating health and landscape elements. It will also show how landscape elements associated with representation need to be assessed with regard toprevention policies.
