What is HHV7?
HHV-7 infection is usually a benign and self-limited disease of childhood and rarely has complications though it may affect the central nervous system. It has been implicated in pityriasis rosea and, like HHV-6 it can also cause exanthem subitum.
-
Signs and symptoms
Both HHV-6B and HHV-7, as well as other viruses, can cause a skin condition in infants known as exanthema subitum, although HHV-7 causes the disease less frequently than HHV-6B. HHV-7 infection also leads to or is associated with a number of other symptoms, including acute febrile respiratory disease, fever, rash, vomiting, diarrhoea, low lymphocyte counts, febrile seizures though most often no symptoms present at all.
-
Epidemiology
HHV-7 infections occur at a later age than HHV-6 infections. About 18% of children are infected with HHV-7 by 1 year of age and 53% by 2 years. Most children are infected between ages 2 and 5 presumably from infected saliva of parents and siblings. HHV-7 DNA was detected in PBMCs from 67%, and in cervical swabs from 3%, of pregnant women.
-
Pathogenesis
HHV-7 has a narrower tissue tropism than HHV-6. HHV-7 infects CD4+ T cells, epithelial cells in the salivary glands, and cells in the lungs and skin. HHV-7 is frequently shed in saliva at high levels throughout life in most adults and children.
-
Clinical Manifestations
Primary HHV-7 infection may be asymptomatic or associated with fever or febrile seizures. In a study of 30 children with HHV-7 viremia, the most common clinical presentation was seizures, which occurred at 12 to 63 months of age. HHV-7 viremia was present in 7% of children with febrile status epilepticus; 5% of patients had primary HHV-6B infection and 2% had virus reactivation.
-
Laboratory Diagnosis
Like HHV-6, the most common diagnostic test for HHV-7 in children is seroconversion based on the detection of antibodies by indirect immunofluorescence assay or ELISA. 52 Detection of HHV-7 in serum or plasma is much less common than for HHV-6.
