What are the major disease that can infect a muskrat?

Muskrats can be susceptible to several diseases, with some of the major ones including tularemia, which is caused by the bacterium Francisella tularensis and can be transmitted to humans, and leptospirosis, a bacterial infection that can affect both animals and humans. They may also experience parasitic infections, such as those caused by various protozoa and helminths. Additionally, muskrats can be affected by viral diseases like rabies, though it is less common. Proper management of their habitats can help reduce the incidence of these diseases.
