Whether a child contracts Kawasaki disease cannot be known before birth, according to Mayo Clinic. Doctors do not know what causes the condition, though a number of theories suggest bacteria, viruses and other environmental factors.
Kawasaki disease typically affects children of Japanese or Korean descent, according to Mayo Clinic. It usually strikes between one and two years of age and is rare in children over eight, claims WebMD. Symptoms include fever lasting at least five days, body rash, red eyes, cracked, red feet and hands and swollen lymph nodes in the neck, according to WebMD. Kawasaki disease is not contagious and most children recover fully from the illness within one or two months, says MedicineNet.
