A fever occurs commonly even with mild infections.
Children often have fever with no other symptoms.
In small children it is important to stop the temperature rising too quickly. This can be achieved by reducing their clothing, ensuring they have lots of fluids and giving them paracetamol, which may be bought from the chemist. Diarrhoea and vomiting usually settle in 3 to 5 days and we would recommend avoiding all food for 12 to 24 hours. Drink plenty of fluids frequently and in small amounts. If symptoms persist for longer than 12 hours in babies and young children you should consult your doctor.
