Leptospirosis is a bacterial disease that affects humans and animals. Animals (cattle, pigs, horses, dogs, rodents and wild animals) spread the disease through their urine. The infected urine can get into water or soil which contaminates the environment. Humans become infected by direct contact with urine from infected animals or contact with contaminated water, soil or food.
