This common childhood virus causes high fever for three to five days. As the fever breaks, a child will develop a red rash on her body that may last for another day or two.
Treatment Because roseola is caused by a virus, antibiotics won't treat it. Instead, check with your pediatrician to see if giving your child a fever-reducing medicine might be a safe option.
Contagious factor Wait until the fever is gone before letting your child play with other kids. Studies show that kids are almost noncontagious, if not completely, by the time the rash appears.
