Roseola, a common cause of fever and rashes in young children

Aside from teething, Dra Saulog advised that another possible culprit of Aki’s fever could be something viral. She said after the fever has subsided, we can expect rashes that would start from the neck and would spread up to his feet. Boy is she right!

The following is from Dr. Sears.


Your one-year-old has had a high fever for the past three days, and naturally you are worried. This morning the fever seems to have subsided, but your child has suddenly broken out with a red rash all over the body. What could this be? Is it serious? Should you rush to the doctor? Here is the Dr. Sears guide to this very common childhood illness.


It is a usually harmless illness caused by a virus. It occurs almost only in children age 3 months to 3 years, most often between 9-12 months. It is probably the most common cause of fever in this age group.


This virus generally causes 3 days of high fever (often over 103). The fever then subsides, and the child breaks out in a flat or bumpy red rash, usually starting around the neck, back and chest, then spreading out. The rash lasts a few days to a couple weeks.

Dr. Sears Clue: Roseola is about the only virus in which the rash appears after the fever breaks.


Sometimes this virus will cause 3 to 7 days of high fever, with no other symptoms and no rash. Some children will have swelling of the glands in the front and back of the neck, runny nose, cough, ear pain, vomiting or diarrhea with this illness. Children can have one or all of these symptoms.

Dr. Sears Clue: The characteristic of Roseola is that infants don’t seem very sick and act almost well when the high fever comes down.
