JDC is currently accepting newborns into the practice. However, so that we can continue to offer our existing patients the care and attention that they deserve, JDC is no longer accepting families with existing children who wish to transfer their care from another practice. This will remain in effect until further notice.

The American Accademy of Pediatrics (AAP) is advising parents to stop giving fruit juice to children in the first year of life, saying the drink is not as healthful as many parents think. Click here for more info and age-group recommendations for fruit juice.
Previously the HPV vaccine was given as a 3-dose series for all eligible-aged children. Now only 2 doses are recommended for children age 9 through 14, with the doses separated by at least 6 months. Children who begin HPV vaccination at 15 years of age and older will still need 3 doses. We will send a reminder call to you when your child is due for their next dose.

What is roseola?

Roseola, also known as "roseola infantum" or "exanthem subitum," is a viral infection that is characterized primarily by a high fever and a rash.

top

What causes roseola?

Human herpesvirus type 6 (HHV6) and, sometimes, human herpesvirus type 7 (HHV7) cause roseola. Both are members of the herpesvirus family of viruses.

top

Who gets roseola?

Almost all children are infected during early childhood with HHV6 and HHV7, but only about one-third of children develop signs of roseola. The peak age for developing roseola is 6 to 15 months of age. More than 95% of cases occur in children younger than 3 years of age.

top

How do HHV6 and HHV7 cause disease?

HHV6 and HHV7 are transmitted from person-to-person by direct contact or by contaminated secretions of the nose and the mouth. These viruses are spread through the blood throughout the body, which causes the rash.

top

What are the common findings?

The majority of children with roseola develop a characteristic illness with a very high fever (from 100F to 103F) for approximately three days, which is followed by the onset of a rash the day that the fever resolves. In contrast to what is usually expected with such a high fever, most children, during the fever, behave quite normally and continue with their usual play activities. Some infants may become irritable and have a decreased appetite. In classic cases, the rash typically appears within 24 hours after the fever resolves and then fades over one to three days; however, only approximately 25% of infected children may actually develop the rash.

top

How is roseola diagnosed?

Roseola is diagnosed primarily on the characteristically high fever followed by the development of the rash once the fever resolves. Unfortunately, this makes it very difficult to diagnose roseola during the course of the fever because, typically, there are no other symptoms.

There is a blood test that is available, but, usually, this is not used for diagnosis because either the illness has resolved completely after a few days, or the diagnosis can be made by the physician with some certainty because of the characteristic high fever followed by the rash.

top

How is roseola treated?

There is no specific treatment for roseola. Antibiotics are not helpful because a virus causes roseola. Viruses cannot be treated with antibiotics. The disease is usually mild with complete recovery. Fever should be treated with acetaminophen or ibuprofen.

top

What are the complications?

The major complication of roseola in children is the development of febrile seizures. During the time of the high fever, especially early in the infection, children may have seizures that are caused by the very high fever. Febrile seizures occur in 2% to 3% of all children, and usually are a problem between 6 months and 3 to 4 years of age. Many cases of febrile seizures that occur only once in a child are probably due to roseola.

top

How can roseola be prevented?

A vaccine for roseola is not available. There is very little information on how to prevent roseola; however, outbreaks are uncommon. The spread of roseola can be prevented by minimizing exposure to children who have symptoms of the disease, and by good handwashing after exposure to the disease.

top

What research is being done?

Research is being conducted on the transmission of human herpesvirus 6 and to characterize how the virus causes roseola.
