Kawasaki disease, also known as mucocutaneous lymph node syndrome, is an autoimmune vasculitis. The main clinical manifestations include persistent fever for five days or more. Other symptoms include conjunctival congestion, dry and cracked lips, strawberry tongue, swollen cervical lymph nodes, and redness and swelling at the tips of fingers and toes. Due to recurrent fever, a light and easily digestible diet is recommended. It is advisable to drink plenty of water and eat vegetables and fruits, while avoiding spicy, stimulating, greasy, and hard-to-digest foods.
