Cholera is an infectious disease caused by the bacterium Vibrio cholerae. The primary mode of transmission is through the consumption of food or water contaminated with the feces of an an infected person. Inadequate hand hygiene, especially after using the toilet, can lead to the spread of the bacterium to food and beverages, thus transmitting the disease to other individuals. However, direct person-to-person transmission of cholera is rare when proper hand hygiene and sanitation rules are followed.
