Leptospirosis is a zoonotic (transmitted from animals to humans) disease of worldwide distribution that is quite uncommon in Wisconsin.
It is caused by several strains of a bacterium called Leptospira. Sickness can range from mild to severe. The sickness is often characterized by the sudden onset of fever, chills, myalgias, and headache and may include conjunctivitis, abdominal pain, vomiting, diarrhea, and skin rashes.
Less frequently, it can result in meningitis, liver and kidney dysfunction, pulmonary involvement, and mental confusion. Severe cases happen more commonly in older people and can result in death.
