It is caused by bacteria that belongs to the genus Leptospira. The bacterias of Leptospirosis are transferred to humans when they get in contact with water that is contaminated with the urine of infected animals. It can be transmitted through cuts of the skin, or through the mucous membranes of the eyes, nose and mouth. It can also be communicated through drinking water or the ingestion of contaminated food. Only in very rare cases, Leptospirosis is transmitted from one human to another. The risk of Leptospirosis infection depends upon the amount of exposure.

The increase of exposure in an area is due to flooding. The people who are at a high risk of infection include pet shop workers, veterinarians, military personnel, survivors of natural disasters, agricultural workers, abattoir workers and meat handlers as per WTO.
