Fifth Disease

What is fifth disease?

Fifth disease is a viral illness that is associated with exanthem. Exanthem is another name for a rash or skin eruption. It is spread from one child to another through direct contact with discharge from the nose and throat. It can also be spread through contact with infected blood. It is moderately contagious and usually does not include a high fever, as seen with some other viral skin conditions.

What causes fifth disease?

Fifth disease is caused by the human parvovirus. It is most prevalent in the winter and spring and is usually seen in children 5 to 14 years of age. Outbreaks of the disease frequently occur in school settings.

What are the symptoms of fifth disease?

It may take between four to 14 days for the child to develop symptoms of fifth disease after being exposed to the disease. Children are most contagious before the rash occurs. Therefore, children may be contagious before they even know they have the disease. Also, about 20 percent of people with the virus do not have symptoms but can still spread the disease. The following are the most common symptoms of fifth disease. However, each child may experience symptoms differently. Symptoms may include:

Warning

Pregnant women who have been exposed to fifth disease need to seek medical attention.

Fifth disease is usually a mild illness. However, parvovirus B19 infection may cause an acute severe anemia in persons with sickle-cell disease or immune deficiencies. There is a small risk of fetal death if fifth disease is acquired during pregnancy.

The symptoms of fifth disease may resemble other conditions or medical problems. Always consult your child's physician for a diagnosis.

How is fifth disease diagnosed?

Fifth disease is usually diagnosed based on a complete medical history and physical examination of your child. The rash and progression of fifth disease is unique, and usually allows for a diagnosis simply on physical examination. In addition, your child's physician may order blood tests to aid in the diagnosis.

Aspirin and the Risk of Reye Syndrome in Children

Do not give aspirin to a child without first contacting the child's physician. Aspirin, when given as treatment for children, has been associated with Reye syndrome, a potentially serious or deadly disorder in children. Therefore, pediatricians and other healthcare providers recommend that aspirin (or any medication that contains aspirin) not be used to treat any viral illnesses in children.
