Acute Communicable Disease Control
Leptospirosis
Leptospirosis is an infection of both humans and animals. It is caused by bacteria called
Leptospira. In humans it causes a wide range of symptoms. Some infected persons may have no
symptoms. Others may have high fever, severe headache, and muscle aches. In severe cases,
people may have jaundice (yellow skin and eyes) from liver failure. Severe disease may also
cause kidney damage and respiratory distress. In rare cases death occurs. Many of these
symptoms can be mistaken for other diseases. Leptospirosis is confirmed by testing of a
blood or urine sample.
