[Leptospirosis is a bacterial zoonotic disease that affects humans
and animals caused by spirochetes of the genus _Leptospira_.
Incubation period of illness is 2 days to 4 weeks. Symptoms include
high fever, severe headache, chills, muscle aches and vomiting, and
may include jaundice, red eyes, abdominal pain, diarrhea, or a rash.
Leptospirosis occurs worldwide, but is most common in temperate or
tropical climates. _Leptospira_ organisms have been found in cattle,
pigs, horses, dogs, rodents and wild animals.
Humans become infected through contact with water, food, or soil
containing urine from these infected animals. The disease is not
known to be spread from person to person. Leptospirosis is treated
with antibiotics, such as doxycycline or penicillin. If the disease
is not treated, the patient could develop kidney damage, meningitis,
liver failure and respiratory distress (see
