Pronounced: lep-to-spy-RO-sisEn Español (Spanish Version)
Leptospirosis is a rare bacterial infection that can be serious. The infection is caused by the bacterium called Leptospira.
Leptospirosis is most common in warm, tropical conditions. It also spreads easily. With prompt and proper treatment, prognosis is usually good. If untreated, complications may develop that can potentially be fatal.
Leptospirosis is caused by contact with fresh water, wet or dampened soil, or vegetation that has been soiled by urine from an infected animal.
When contact is made with the contaminated material, the bacteria enter the body through open sores or wounds in the skin, or through mucous membranes. When the bacterium has entered the body, it flows into the bloodstream and throughout the body, causing infection.
