Management
The mainstay of treatment is timely and adequate rehydration. For mild dehydration, patients may take oral rehydration salts (ORS) fluid. Severe dehydration cases usually require intravenous rehydration to replenish fluid and mineral loss. For severe cases of diarrhoea, antibiotics may be used.
