How is Cholera transmitted ?

Cholera is transmitted by drinking water or eating food contaminated with the cholera bacterium, Vibrio cholerae. 

Raw or undercooked seafood may be
a source of infection in areas where cholera is prevalent.

Cholera outbreaks can occur sporadically in any part of the world where water supplies, sanitation, food safety and hygiene practices are inadequate. 

Overcrowded communities with poor sanitation and unsafe drinking-water supplies are most frequently affected.

Floodwaters can carry V. cholera and contaminate drinking water supplies. Vibrio cholerae can resist brackish water and coastal water environment with high salinity. 

The disease is not likely to spread directly from one person to another; therefore, casual contact with an infected person is not a risk for becoming ill.

Travellers at risk of cholera infection may be immunized with the killed whole organism vaccine, which offers about 60% protection for 3-6 months.

In Zimbabwe the National Water Authority is failing to supply water to large parts of the urban areas. This has resulted in residences drawing on Boerhole Water and others purchasing from borehole owners. My question is what is the risk of being infected by the Cholera Bacteria especially in schools who use the water to wash with but not to drink?
