Hives can come when the body is fighting a virus, they usually come and go when the body is fighting a virus. My little one just appeared with them one day all over her leg, they dissappeared and then reappered on her face....long story, called the doctor and her recommended benadryl every 6 hours until that day. She did have some sort of bug. Also, strep throat can present with hives.
