I'm 21 and worried that i have roseola, what symptoms should i look for?

Fever & rash: Roseola is a common frustrating virus , usually experienced in childhood. 3-7 days of varied fevers that can be sustained @105 in toddlers & followed a lacy rash over the trunk & extremities.It often amplifies after a bath or shower.The temperature usually disappears as the rash emerges & the rash may take a couple weeks to fade.Other than feeling rotten with the fever itspretty benign in adults.
