Zoonotic Diseases in Wildlife Populations
Grand Canyon National Park is an area of astonishing natural beauty, a place where people can experience solitude and natural landscapes, and a vibrant ecosystem of diverse plants and wildlife species. As is true for all wild places, natural hazards are an inherent part of the Grand Canyon landscape.

Many zoonotic diseases have flu-like symptoms, including fever, headache, and chills. When you suspect that may have been exposed to a zoonotic disease and are seeking medical care, it is essential that you tell your physician that you may have been exposed to infectious agents carried by wildlife or their parasites.
Zoonotic diseases are infectious diseases that can be transmitted between animals and humans. Wildlife species in and around Grand Canyon National Park may carry a wide variety of such diseases, including, but not limited to, plague, Hantavirus, rabies, and tick-borne relapsing fever, which has been documented only on the North Rim.
