A sky-high fever accompanied by a rash caused by a virus that generally affects children – these are the major symptoms of roseola. Fortunately, though, roseola is common and typically isn't life-threatening. Because it’s common among kids 6 months to 2 years old, it’s a good idea to familiarize yourself with it – especially if you have a child younger than age 6.
It usually starts with a tired or cranky child. A sore throat sometimes follows and then there's a fever. Up until this point, most parents believe their child has a cold. Then they notice a rash on the body or blisters in or around the mouth. If your child is experiencing these symptoms, especially in early fall, you may have a case of hand, foot and mouth disease on your hands.
