** Thanks for contacting HCM with your health concern 1. If you develop a rash with flu like symptoms you should suspect a viral infection since rashes are common with them especially in children and should contact your GP immediately, as sometimes a typical rash helps a doctor to diagnose which virus is causing the illness 2. There is no specific treatment for the rash itself, treatment should be aimed at other symptoms, like: - paracetamol to relieve fever - antihistamines to relieve itching - adequate bed rest - semi solid or liquid diet - plain water,lime water,coconut water or electral water - soft rice with milk, palin daal,boiled vegetables, toast jam,cornflakes, apple, banana,pear,watermelon,biscuits 3. See a Doctor if you are concerned that rash or symptoms are serious
