Leptospirosis, also called Weil’s disease, is a disease caused by the Leptospira bacteria. The disease is carried mainly by rodents, especially rats and similar small mammals. The bacteria are found in the urine of the infected animals.

Infection is through direct or indirect exposure to urine contaminated water or soil. Therefore those with occupational or recreational exposures are at greatest risk, such as:

  • farmers
  • veterinarians
  • sewage workers
  • sailors
  • divers
  • outdoor swimmers
