Advice for Travellers
Leptospirosis is caused by contact with fresh water, wet soil, or vegetation that has been contaminated by urine of animals that are chronically infected. The infection is transmitted through unhealed breaks in the skin, the eyes, or the mucous membranes. Rats, dogs, cattle, and pigs are the usual reservoirs for this organism. Leptospirosis occurs worldwide and frequently follows flooding after heavy rains.
Travellers may be at risk if swimming or engaging in water sports in infected fresh water or wading through flood water.
