### Human:\nis hand foot mouth disease the same as thrush. is hand foot and mouth disease caused by the same virus as thrush? would l-lysine help this condition? .\n\n### Assistant: no. they are not the same. hand foot and mouth disease is caused by a coxsackie virus. thrush is caused by yeast. l-lysine would be worthless in treating either one. hand foot and mouth disease will self-resolve and does not require treatment. thrush may also self-resolve but there are prescription anti-yeast medications that really help make it go away sooner.
