Infectious risks associated with outdoor sports activities

Abstract

In France, outdoor sports and activities account for 36% of sports engagement, making outdoor venues the most popular settings for sports participation. Discussing the links between sports and health almost always highlights the beneficial impact of engaging in sports. However, due to a lack of specific notifications, infectious risks are not subject to epidemiological monitoring, and need to be better understood. Since the practice of outdoor sports has become part and parcel of many individuals’ daily routines, it is essential to more accurately characterize the knowledge we have gained about the risks associated with exposure. However, directly associating the practice of a sport with an elevated risk of infectious diseases is a challenging endeavor. Sociological factors based on risk awareness and adoption of protective behaviors in response to the risk are crucial to the orientation of prevention efforts.

This review deals with several (bacteriological, viral, parasitic, and mycological) infectious risks related to outdoor activities practiced in a natural field via contamination routes such as tick-bite, enteric pathogen, skin, and aerosol transmission. We have also detailed a number of preventive measures taking into account the outdoor setting (e.g., vaccination).
