Roseola Sixth Disease Virus Symptoms Treatment Causes

Roseola

Roseola is also known as roseola infantum or roseola infantilis. The rash appears suddenly after the fever, so it is commonly called exanthem subitum.

Roseola was once called "sixth disease" because it was the sixth disease children typically got and lasted about six days. However, this name is mostly forgotten.

What causes roseola?

Roseola is primarily caused by human herpesvirus 6 (HHV-6) and occasionally by human herpesvirus 7 (HHV-7).

What are the symptoms of roseola?

The symptoms of HHV-6 or HHV-7 infection vary depending on the patient’s age.

  • Infants and toddlers typically develop a sudden high fever (103-104 degrees) that lasts 3-5 days.
  • The child may also experience irritability, swollen glands in the neck, runny nose, puffy eyelids, and mild diarrhea.

Most people infected with HHV-6 or HHV-7 have no symptoms. Only a few individuals develop noticeable symptoms, and they usually recover without complications. However, individuals with weakened immune systems, such as newborn infants, chemotherapy patients, and those with HIV-AIDS, may experience a more severe form of the disease.

How is roseola transmitted?

Roseola spreads from person to person through oral secretions.

  • The incubation period between exposure and symptoms is nine to ten days.
  • HHV-6 and HHV-7 only infect humans and are not affected by seasonal variations.

If the fever is not causing discomfort, it does not need treatment. Acetaminophen or ibuprofen can be used to lower the fever, but there is no need to wake a sleeping child to treat the fever. Aspirin should never be given to children or adolescents for fever.

A child with a fever should be kept comfortable and not overdressed. Bathing with tepid water can help reduce fever. Alcohol should not be used for sponging as it can be inhaled and cause harm.
