I have a rash since I had a fever?

It is recommended to use a fragrance-free moisturizer like Aveeno and a mild soap like Dove without fragrance for the next few days. Apply the moisturizer as often as needed throughout the day. After showering, gently pat the skin dry instead of rubbing it, leaving a thin layer of moisture, and apply the moisturizer within 5 minutes of showering. Consult with your pharmacist about trying an antihistamine depending on the severity of your symptoms. If the situation persists for more than 7 days or worsens, it is advisable to see a doctor for a thorough evaluation of your condition as a precaution.
