What causes Leptospirosis?
The Leptospira bacteria can be found in fresh water that has been contaminated by animal urine. The infection occurs in warmer climates.
Leptospirosis is not spread from person to person, except in vary rare cases. It occasionally spreads through sexual intercourse, breast milk, or from a mother to her unborn child.
Risk factors include:
- Occupational exposure -- farmers, ranchers, slaughterhouse workers, trappers, veterinarians, loggers, sewer workers, rice field workers, and military personnel
- Recreational activities -- fresh water swimming, canoeing, kayaking, and trail biking in warm areas
- Household exposure -- pet dogs, domesticated livestock, rainwater catchment systems, and infected rodents
Leptospirosis is rare in the continental United States. Hawaii has the highest number of cases in the United States. Recent out break of leptospirosis is reported in Bronx, New York and found 3 cases in the months January and February, 2017.
Who is at highest risk?
Outbreaks of leptospirosis are usually caused by exposure to water contaminated with the urine of infected animals. Many different kinds of animals carry the bacterium; they may become sick but sometimes have no symptoms. Leptospira organisms have been found in cattle, pigs, horses, dogs, rodents, and wild animals. Humans become infected through contact with water, food, or soil containing urine from these infected animals. This may happen by swallowing contaminated food or water or through skin contact, especially with mucosal surfaces, such as the eyes or nose, or with broken skin. The disease is not known to be spread from person to person.
