Cholera infection can be prevented in a community by:
Sanitary disposal of faeces.
Pure drinking water.
Uncontaminated food supply (particularly seafood and vegetables).
Sanitary preparation of food in commercial establishments and homes.
Cleanliness are the most effective ways in preventing and controlling outbreaks.
Routine treatment of a community with antibiotics, or "mass chemoprophylaxis", has no effect in controlling the spread of cholera.
Limited stocks of two oral cholera vaccines that provide high-level protection for several months against cholera caused by V. cholerae O1 have recently become available in few countries.
