All age groups & both sexes are affected (except exclusively breastfed babies).

Cases are being reported from urban & rural area. The vibrio is destroyed in an acidity of pH 5 or lower. Conditions that reduce gastric acidity may influence individual susceptibility Movement of population (e.g. pilgrimages, marriages, fairs and festivals) result in increased risk of exposure to infection.

The incidence of cholera tends to be highest in the lower socio economic groups and this is due to poor hygiene.
