Cholera [SEP] Transmission
Cholera bacteria have been found in shellfish and plankton. Transmission is usually through the fecal-oral route of contaminated food or water caused by poor sanitation. Most cholera cases in developed countries are a result of transmission by food, while in the developing world it is more often water. Food transmission can occur when people harvest seafood such as oysters in waters infected with sewage, as "Vibrio cholerae" accumulates in planktonic crustaceans and the oysters eat the zooplankton. People infected with cholera often have diarrhea, and disease transmission may occur if this highly liquid stool, colloquially referred to as "rice-water", contaminates water used by others.
