Currently, there is no specific treatment for hand, foot and mouth disease. It will usually clear up by itself in a week without treatment, so disease management typically focuses on relieving the symptoms. If a patient has trouble eating due to an excessively sore throat, they should be given lots of water, milk and soft food. In more severe cases where the patient becomes exhausted, they should be admitted to the hospital where they can receive intravenous fluids.
Once the condition has cleared up, there is always a chance that it can return because, even though anyone infected with hand, foot and mouth disease will develop immunity to the specific strain of the virus they have contracted, this does not prevent them from becoming infected by a different strain of the virus.
