What does hand, foot and mouth disease look like?

The rash can involve the palms, soles, fingers, toes, buttocks, legs, or arms, and it may not look identical on both sides. Mouth sores can occur on the tongue, gums, cheeks, or palate. Spots may begin as red marks and become fluid-filled before drying. Appearance alone cannot confirm the cause: other rashes can overlap, and a clinician considers the child’s symptoms, age, contacts, and examination.

Take note of where the spots started and whether they are spreading, crusting, or becoming painful. Encourage cool drinks and soft foods if the mouth is sore. Do not burst blisters or apply unapproved creams. Wash hands after touching the rash, clean frequently handled surfaces, and avoid sharing towels or eating utensils. A clear description or dated photograph may help a clinician assess change over time, but it does not replace an examination.

Seek prompt advice when a rash is rapidly spreading, very painful, hot, swollen, or draining pus, or when the child is not drinking well. Urgent help is needed for breathing problems, a seizure, severe drowsiness, confusion, or a stiff neck with severe headache. Get assessment for purple or bruise-like spots that do not fade when pressed, especially if the child appears seriously unwell.

Ask which features support hand, foot and mouth disease, whether the mouth sores could affect hydration, and what changes should prompt review. Share when the rash appeared and any fever or exposure to an unwell child.
