Multi-Patient Rabies Exposure on a Colorado River Rafting Expedition: Urgent vs. Emergent Transport Decision Making in an Austere Setting.

We present a case of rabies exposure on a private river rafting trip on Grand Canyon National Park's Colorado River. Five individuals were exposed to an erratically acting bat; one of the individuals sustained a direct bite to the upper lip while sleeping. This case illustrates the challenges of austere medical care and evacuation in remote conditions while highlighting the importance of risk mitigation considerations in all austere situations.
