What is leptospirosis?
Leptospirosis is a rare bacterial disease caused by bacteria of the genus Leptospira. Humans contract leptospirosis by swallowing contaminated water or food, or through contact with contaminated soil, water or food. Water, soil and food can become contaminated by mixing with animal urine that contains Leptospira bacteria.
Animals that can be infected with Leptospira include domestic animals, such as cows, pigs, horses and dogs. Rodents and other wild animals can also be infected and contaminate bodies of fresh water. Humans who participate in recreational or occupational activities around infected animals are at risk of coming in contact with contaminated water, soil or food. Contaminated water is the most frequent cause of leptospirosis.
Leptospirosis is known by many names including hemorrhagic jaundice, infectious jaundice, mud fever, and swamp fever. It is rare in most developed countries including the United States. It is more likely to occur in warmer and tropical climates.
Symptoms of leptospirosis may begin two to 26 days (on average, 10 days) after exposure to a contaminated source. Early treatment of leptospirosis is usually successful and the outlook for recovery from mild cases is good.
In some cases, leptospirosis can progress to a serious or life-threatening situation, especially if treatment is not started early in the course of the disease. Complications include meningitis and Weil’s disease, which causes organ damage or failure. Seek prompt medical care if you, or someone you are with, have any symptoms suggesting leptospirosis after drinking untreated water, or have traveled to a developing country and have flu-like symptoms, such as nausea, vomiting, cough, headache or fever.
What are the symptoms of leptospirosis?
