The infamous plague is a deadly, infectious, rodent-borne disease found in the western U.S., South America, Africa, and Asia. Plague can be spread by direct contact with an infected rodent, or through the bite of an infected flea. A range of rodents can carry plague, including wild rodents, prairie dogs, squirrels, and chipmunks.

Rat-Bite Fever

Rats and mice can carry rat-bite fever, a bacterial infection that is found worldwide. It can be spread through a scratch or bite from an infected rodent, or from contact with a dead rodent. Eating or drinking water or food that has been contaminated by rat feces can also transmit rat-bite fever.

Hantavirus Pulmonary Syndrome

Diseases Carried by Rodents

Hantavirus Pulmonary Syndrome is a virus that is transmitted from a select number of rodents, such as the deer mouse, cotton rat, rice rate, and white-footed mouse. This disease occurs throughout North and South America, and is the result of breathing in air that is contaminated with infected rodent feces or urine. The disease can also be spread through a bite wound, or by making direct contact with rodents or their fecal matter.


Rats and mice can transmit this bacterial infection worldwide. Caused by eating or drinking food or water that has been contaminated by rat feces, salmonellosis can cause severe dehydration due to vomiting, diarrhea, and fever in humans.
