The amount of salt and water loss resulting in dehydration is higher in patients with cholera than other types of diarrhea (Molla et al. 1981). However, loss of potassium is higher and loss of other salts is lower in rotavirus diarrhea compared to other diarrheal diseases. Therefore, kids who commonly suffer from rotavirus diarrhea should be given extra plain water and/or breast-milk in between ORS to prevent hypernatremia (a salt overload).
