What is leptospirosis?

According to the World Health Organization (WHO), leptospirosis is a disease caused by leptospira bacteria, which is transmitted by rodents.  The infection spreads to humans through direct contact with or water and soil contaminated by the urine of infected rodents. It does not spread from human-to-human contact.

Common symptoms of rat fever include a high fever of up to 104 degrees F, headache and chills, severe muscle pain, skin rashes, diarrhea, and jaundice.

Without proper medical treatment, rat fever can cause multi-organ damage including damage to the kidneys, lungs, and liver. It can also lead to fatalities.
