I'm 14–Is is possible that I have roseola?
A few days ago, I suddenly got a fever of 102 which lasted for 2 days. Then yesterday, I noticed a red, spotty rash all over my body that didn’t itch. The symptoms of roseola listed online seem to match mine, but it says that it is most common in babies from 6 months to 4 years. I’m 14, but could I still have it? Thanks!

i highly doubt theres a chance, as its a virus among small children. by what i have read its a hsv virus and belongs to the herpes family, i am guessing you could get this virus from the mother, during birth and thats why young children get it, only a guess.
but you may just have symptoms to a completly different virus, type in your symptoms into google.
i did some research;
Roseola (contagious) –
A flat, rosy red rash on the chest and abdomen caused by a herpes virus. There is high fever 2 to 4 days before the rash. It commonly affects children between the ages of 6 months and 3 years. The child may feel only mildly ill during the fever. Roseola is infectious for 5 days after first symptoms occur.
is this correct?
otherwise known as Exanthem subitum.

i would most probably just go to the doctors, they will know what it is and treat it best.
