Tick ecology and Lyme borreliosis prevention: a regional survey of pharmacists’ knowledge in Auvergne-Rhône-Alpes, France

International audienceThe most prevalent vector-borne diseases in Europe are caused by tick-borne pathogens, such as bacteria of the genus Borrelia that cause Lyme borreliosis. In this context, retail pharmacists are frequently the first medical source of information in the event of a tick bite. The objective of this study was to assess pharmacy professionals' knowledge about both tick ecology and the appropriate measures for tick bites and Lyme borreliosis prevention. It was based on an online survey of 364 pharmacists and pharmacy assistants located in the Auvergne-Rhône-Alpes region of France. The results showed solid knowledge about preventive measures for tick bite and Lyme borreliosis, but weaker knowledge about tick biology (hosts, suitable habitats, favorable conditions for tick activity, etc.). In particular, several stereotypes were observed in the responses of the pharmacy professionals. These appear to result from a social construction of the knowledge on ticks and tick-borne diseases previously shown to the general population in the region. The results highlight the need for continuous training about ticks and tick-borne diseases for healthcare professionals serving local populations that live in endemic areas
