Contagion and contagiousness refers to how easily the spread of Cholera is possible from one person to another. Other words for contagion include "infection", "infectiousness", "transmission" or "transmissability". Contagiousness has nothing to do with genetics or inheriting diseases from parents. For an overview of contagion, see Introduction to Contagion.
