Hi, my 5 yrs old son have Scarlet fiver. Fiver comes and goes, rash over his body, fiver 102-103. I just came back from the Dr. who prescribed a antibiotics. but fiver still on. What is the best way to lower his temperature? I give lots of cool water, and put in his forehead a tow with ice. I don t know what more to do. Thank you Mary Davis,
