Hello there.
Hand, foot and mouth disease is caused by a virus.
Usually only supportive treatment is required like fever reducing drugs, warm water baths etc.
Usually this lasts for about a week to 15 days and is self resolving.
It will gradually reduce by itself because the body will fight against the virus and gain immunity.
Consult a paediatrician periodically till it subsides.
