Why are there itchy red bumps in face, chest and forehead of five years old?

Hi doctor,

This is in regard to my daughter who is 5 years old. Four days back suddenly she developed a fever. The fever was around 100 degrees F. Yesterday her fever subsided and now she does not have the same. She did not have a cough, cold, etc. But she lost her appetite and she also had a left eye white area red. The redness also has disappeared now. She did complain of a little bit of nausea and headache. But yesterday everything subsided and she recovered well. But, yesterday night we saw red bumps around her face, forehead, and chest area. It itches sometimes. I am attaching the image for your reference. These bumps are slightly raised. Rest she seems fine now. Her appetite has increased as well.

On the second day of her fever, she fainted briefly (a little bit of saliva came out from her mouth) for 5 to 10 seconds. She recovered quickly in a minute or two. This happened in the early morning when she woke up and stood. She had a moderately high fever throughout the night.
