Risk of Exposure

Leptospirosis occurs worldwide, but is most common in temperate or tropical climates. It is an occupational hazard for many people who work outdoors or with animals, such as:

  • Farmers
  • Mine workers
  • Sewer workers
  • Slaughterhouse workers
  • Veterinarians and animal caretakers
  • Fish workers
  • Dairy farmers
  • Military personnel

The disease has also been associated with swimming, wading, kayaking, and rafting in contaminated lakes and rivers. As such, it is a recreational hazard for campers or those who participate in outdoor sports. The risk is likely greater for those who participate in these activities in tropical or temperate climates.

In addition, incidence of Leptospirosis infection among urban children appears to be increasing.
