Roseolovirus

Hello.
My name is Roseolovirus.
Sometimes I'm called Human Herpes Virus 6 (HHV-6) or '6th disease'.
I'm part of the Herpesviridae family.

I mostly infect babies and children.
First you get fever, but it doesn't last long.
When thats gone, I give you a rash called Exanthem subitum, or Roseola infantum.

I got my name because people thought my rashes were as red as roses.
