Hand, foot and mouth disease

Hand, foot and mouth disease is a common viral infection in young children, although adults can get it too. It causes mouth ulcers and a rash of spots on the hands and feet. It spreads easily through coughs, sneezes, poo and touching the blisters. It is not related to foot and mouth disease in animals.

It usually gets better on its own within 7 to 10 days. Drinking fluids, soft foods and pain relief help.

Washing hands often helps stop it spreading.
