Skin Rashes

My baby who is 1 year old had an on and off slight fever for 2 days starting Monday. She doesn't have cough or colds. Then from Wednesday, she didn't have fever at all, and she's still playing and eating normally, but today, she developed some skin rashes. There's a lot on her face and few on her back. Her pedia's not available for the holidays and other clinics nearby don't have as well. I would just like to have an idea on what might be happening to her but will still take her to the first doctor that will be available this week. Thank you.
