Below is a look at some other familiar diseases being monitored. Coyotes may even help mitigate certain diseases, like Lyme, by keeping rodent populations down and diversity up.

Sometimes the diseases listed here are monitored not because coyotes host, transmit, or perpetuate them, but rather because coyotes are an excellent surveillance species that can provide information regarding general pathogens in the environment. It is important to note that by effectively vaccinating your pets against certain diseases, you are helping to break transmission potentials before they start your pet's risk to diseases carried by wildlife populations in fact can be a direct result of proper domestic animal management. In some cases, positive results from serology may only serve to indicate exposure to a disease, and other diseases have multiple forms of which only some are zoonotic. While these diseases may occur in fairly high rates in coyotes, they are rarely transmitted to people or pets because of low pathogen survival rates in the environment or because the coyote may be a "dead-end" host. These diseases are important to study because they can affect people or pets.

Through serological testing (using blood to identify disease), the Cook County Coyote Project looks primarily for the presence of these diseases in the coyote population: canine parvo, canine distemper, toxoplasmosis, Lyme, and Leptospirosis.
