What is Roseola?
Roseola is a viral illness in young children, most commonly affecting those between the ages of 6 months and 2 years. Stockton had several days of high fever, followed by a distinctive rash just as the fever broke.
Who gets it?
Almost all cases of roseola occur in children before their third birthdays. The peak age is between 6 and 15 months. Healthy babies are born with protective antibodies from their mothers, but these begin to disappear when the baby is 4 to 6 months old. By 15 months, most babies have protective antibodies that they have made themselves. These will last a lifetime.
Fewer than half of children ever get roseola. Nevertheless, almost all children have had HHV-6 infections by age 3. For the majority, who never get the rash, the HHV-6 infection usually causes a fever, perhaps with other symptoms. It is a common cause of baby’s first fever.
