DD had a 102 fever on Mon and Tuesday. Yesterday (Thursday) this rash showed up. She's got pretty sensitive skin and gets heat rash pretty easily, but today it looks like the rash spread. From what I've read about roseola, the fever is usually higher and the rash shows up right afterwards.

For those that have dealt with roseola.....does this look like it to you?

I know there's not much I can do about it since it's a virus. How long does the rash usually last?
