How common is fever in hand, foot and mouth disease?

Hand, foot and mouth disease is a viral illness that often starts with fever, reduced appetite, tiredness, or a sore throat. Small painful sores may then appear in the mouth, while spots or blisters can develop on the hands, feet, or other skin areas. A child may have fever before the skin changes are easy to see, so the pattern can become clearer over time. Fever alone does not identify the cause; many common illnesses can raise body temperature.

Offer frequent drinks and choose cool, soft foods if mouth sores make eating uncomfortable. Rest, light clothing, and a comfortable room can help. Check the temperature with a suitable thermometer and follow the label or a clinician's instructions for any fever medicine; use a child-appropriate product and dose. Avoid sharing cups, utensils, towels, or close-contact items while the illness is active, and wash hands after helping with toileting or wiping secretions.

Seek urgent medical help if the child is difficult to wake, has trouble breathing, has a seizure, develops a stiff neck, or cannot keep fluids down. Arrange prompt assessment for signs of dehydration such as very little urine, a dry mouth, no tears, or unusual sleepiness. Contact a clinician if fever is persistent, the child is getting worse, or you are unsure whether the rash and mouth sores fit this illness.

Ask whether the examination fits hand, foot and mouth disease, how to manage mouth pain, which fluids and foods are suitable, and which changes should prompt a return visit.
