Leptospirosis
Description
A disease caused by an infection with the gram-negative bacteria Leptospira. In the first phase, this disease is characterised by generalised illness (fever, chills, or myalgias) or individuals may be asymptomatic; in the second phase, the heart, liver, kidneys, or brain may be affected by the infection (symptoms are dependent on the site affected). Transmission is by ingestion of contaminated food or water, droplet transmission, or direct cutaneous contact. Confirmation is by identification of Leptospira in samples from the affected individual.
