What is leptospirosis?

Leptospirosis is an infectious disease caused by a type of bacteria called a spirochete. Leptospirosis can be transmitted by many animals such as rats, skunks, opossums, raccoons, foxes, and other vermin. It is transmitted though contact with infected soil or water. The soil or water is contaminated with the waste products of an infected animal. People contract the disease by either ingesting contaminated food or water or by broken skin and mucous membrane (eyes, nose, sinuses, mouth) contact with the contaminated water or soil.

Leptospirosis occurs worldwide, but it is most commonly acquired in the tropics. The U.S. Centers for Disease Control and Prevention states 100-200 cases of leptospirosis are reported each year in the United States, with about 50% of cases occurring in Hawaii. Although the incidence in the United States is relatively low, leptospirosis is considered the most widespread disease that is transmitted by animals in the world.

A 2010 outbreak in Michigan caused serious illness in numerous pets, raising concern for the local human population. In 2009, typhoons hit the Philippines, causing a leptospirosis outbreak. The Philippines Department of Health then reported 1,887 cases of leptospirosis, which resulted in 138 deaths.
