Plague infection in people is uncommon and there have not been any reported cases. Common symptoms of plague include fever, swollen and tender lymph nodes, chills, and extreme exhaustion. Anyone experiencing these symptoms should promptly contact their health care provider. Although plague can cause serious illness, it can be effectively treated with antibiotics, especially when diagnosed early. Dogs that are exposed to plague do not usually get sick, but can transport infected fleas and expose people.
