Cholera Fast Facts

Haitians wash clothes in a stream in Port-au-Prince. The widespread use of rivers has been linked to the country's deadly cholera outbreak.

(CNN)Here's a look at cholera, an acute diarrheal illness which kills thousands of people worldwide each year.

Cholera is contracted by consuming food or water contaminated with the fecal bacteria Vibrio cholerae.
Dehydration from rapid loss of body fluids is the reason the disease can be so deadly if the patient is not treated.
    The disease's short incubation period of two hours to five days increases the likelihood of outbreaks.
    80% of cholera cases can be treated and resolved with oral hydration salts.
    There are three two-dose oral cholera vaccines available, Dukoral, ShanChol and Euvicho, but it may take weeks for an individual to have full protection.
    Cholera is rare in industrialized nations.
    People who live in areas with poor or inadequate water treatment, sanitation and hygiene practices are more likely to get the disease.
