The social representations of diagnosing Lyme disease

Abstract

Social science studies on the controversy surrounding Lyme disease (LD) focused on the opposition between the “mainstream” and biomedical approach on one side and the “Lyme-literate” one on the other side, the latter claiming the existence of the chronic form of LD. The qualitative and exploratory study ‘C18-48 Quali-Explo-PIQTIQ’ (2019) investigated the social representations of LD in patients bitten by a tick. Twenty-four semi-structured interviews were conducted in three French medical units. Thematic and patient trajectory analyses were performed. Our results showed that, after the tick bite, some patients presented an “illness without disease” condition, characterised by uncertainty. In some cases, they consulted “Lyme-literate” health providers and received a diagnosis of chronic LD. This diagnosis was obtained by prescribing unassessed biological testing, providing an objective result and clinical categorisation. Unlike literature on the “Lyme-literate” approach, this diagnostic procedure involved some biomedical operations.
