I, too, think it could be Kawasaki Syndrome. In any case, I'd drive him to the best hospital within 200 miles — “best” meaning affiliated with a university and highly ranked — and go to the emergency room and wait however long you have to until he's admitted. Then, refuse to check him out until until he is well.

A temp of 103 PLUS the peeling skin means needs treatment NOW.
