Health is an often-overlooked issue in the touristic development of territories. However, the recent pandemic linked to Covid-19, by bringing the tourism sector to a halt, has revealed the importance of health issues for this economic sector. This book deals with the interaction between tourism and health in all its facets and offers a complete overview of the subject, the beginnings of which date back to Antiquity. The arguments presented here are based on a back-and-forth approach between tourism studies and health sciences. Various themes are thus addressed, such as health risks, health issues for travellers linked to tourism practices, medical tourism, health mobility and the global processes that accompany it, as well as the impact of tourism development on public health in destinations. A Back and Forth Between Tourism and Health highlights the need to include the health dimension in tourism planning and invites a paradigm shift in thinking about the tourism sector.
