'''Cholera''' is a [[diarrhea]]l [[disease]] caused by intestinal infection with the [[bacterium]] ''Vibrio cholerae''. The infection is often [[symptom|asymptomatic]], but can be quite severe. Approximately one in twenty infected patients exhibit profuse watery diarrhea, vomiting, and leg cramps. In these persons, rapid loss of body fluids leads to [[dehydration]] and hypovolemic shock. Without treatment, death can occur quickly. <ref name="cdc">[http://www.cdc.gov/nczved/dfbmd/disease_listing/cholera_gi.html Centers for Disease Control]</ref>
