Hello, my son is 7 years old and in Feb and 3 weeks later in March he was diagnosed with scarlet fever. Beginning 6 days ago he developed symptoms of a cold, and now showing signd of scarlet fever again. His primary is saying its Kawasaki however he shows no signs of heart problems and his fever doesnt last past 3 days. I do not believe that it is kawasaki, however why is he getting sick so much and immediately developing scarlet fever each time.
