Leptospirosis

(Weil's Disease; Icterohemorrhagic Fever; Swineherd's Disease; Rice-Field Fever; Cane-Cutter Fever; Swamp Fever; Mud Fever; Hemorrhagic Jaundice; Stuttgart Disease; Canicola Fever)

Pronounced: lep-to-spy-RO-sis

Definition

Leptospirosis is a bacterial infection.

Causes    TOP

Certain bacteria cause the infection. Animals that have it pass urine to water, soil, and plants. It then goes into your body by direct contact. This means though your bodily fluids, cuts in the skin, or by drinking it.

Risk Factors    TOP

Leptospirosis occurs worldwide, but is most in common tropical places. Your risk is highest if you live in or travel to these places.

Your risk is also higher if you, or your pets or livestock play or work in or near contaminated soil, plants, or water such as with:

  • Camping
  • Swimming or wading
  • Boating, canoeing, or kayaking
  • Farming
  • Mining
  • Caring for animals
  • Working in sewers
  • Working in the military

Symptoms    TOP

You may not have symptoms. If you do, you may have:

  • Fever
  • Muscle aches
  • Belly pain
  • Diarrhea
  • Red eyes
  • Rash
  • Dry cough
  • Yellowing of the skin and whites of the eyes—jaundice

Rare, but serious problems involve the lungs and kidneys.

Diagnosis    TOP

The doctor will ask about your symptoms, and health and travel history. You may have:

Treatment    TOP

Care may start in a hospital. Antibiotics treat the infection. You may also need other care to support organ function, but this is rare.

Prevention    TOP

To lower your chances of infection:

  • Lessen time in soil, plants, or water where animals pass urine.
  • Wear clothing that protects your skin, as well as waterproof boots or waders.
  • Use bottled water. If you’re unsure if water is safe, don’t drink it or use it to wash food.
