Hello,
From the symptoms it looks like a viral infection. Make your child wear cotton clothes and apply calamine lotion on the rash. If the symptoms worsen then get it checked from a dermatologist.

It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
