Signs and Symptoms of Leptospirosis

In humans, it causes a wide range of symptoms, while some infected persons may have no symptoms at all. Symptoms of leptospirosis include
  • Anemia.
  • High fever.
  • Severe headache.
  • Chills.
  • Muscle aches
  • Vomiting.
  • May include jaundice (yellow skin and eyes).
  • Red eyes.
  • Abdominal pain.
  • Diarrhea.
  • Rash.
If the disease is not treated, the patient could develop kidney damage, meningitis (inflammation of the membrane around the brain and spinal cord), liver failure, and respiratory distress. In rare cases, even death could occur. Many of these symptoms can be mistaken for other diseases. Leptospirosis is confirmed by laboratory testing of a blood or urine sample. People with leptospirosis are usually quite ill and are often hospitalized.
