Prophylaxis:

Cholera is spread by contamination of food and water and rarely through contact with infected people or sick unless it is not given basic hygiene measures such as washing hands after evacuating and before eating. Health measures such as the control and storage of food and water under hygienic conditions are more than enough to prevent the occurrence of these outbreaks, and provide the necessary information to the public about modes of transmission and sanitary measures to avoid contagion.

The excreta of carriers and patients should properly handled to avoid further spread of the microorganism. For those people who are in contact with carriers of Vibrio cholerae, suggests making 1g tetracycline every 24 hours for five days. The use of the vaccine with dead vibrios gives partial protection and limited, a situation that has conditioned its inefficiency to limit disease outbreaks from one country to another.
