El herpesvirus humano 7 o HHV-7 (especie Human betaherpesvirus 7) es una especie de virus de la familia Herpesviridae. Se caracteriza por una organización de su genoma similar al del herpesvirus humano 6 (HHV-6); de hecho, se ha descrito una actividad antigénica cruzada entre ambos virus.
Human betaherpesvirus 7 (HHV-7) is one of nine known members of the Herpesviridae family that infects humans. HHV-7 is a member of Betaherpesvirinae, a subfamily of the Herpesviridae that also includes HHV-6 and Cytomegalovirus (HHV-5 or HCMV).

Herpesviridae is a large family of DNA viruses that cause infections and certain diseases in animals, including humans. [1] [2] [3] The members of this family are also known as herpesviruses. The family name is derived from the Greek word ἕρπειν ( herpein 'to creep'), referring to spreading cutaneous lesions, usually involving blisters ...
The Herpesvirales is an order of dsDNA viruses (Baltimore group I) with animal hosts, characterised by a common morphology consisting of an icosahedral capsid enclosed in a glycoprotein-containing lipid envelope. Common infections in humans caused by members of this order include cold sores, genital herpes, chickenpox, shingles, and glandular ...
The discoveries of Human herpesvirus 6 variant A (HHV-6A), Human herpesvirus 6 variant B (HHV-6B) and Human herpesvirus 7 (HHV-7) followed the development of methods for activation and long-term culture of peripheral blood T lymphocytes. Based on their shared biological properties and nucleotide sequences, HHV-6A, HHV-6B, and HHV-7 are classified as members of the roseolovirus genus of the ...

Oct 30, 2023 · HHV-7 belongs to the Roseolovirus genus of the herpesvirus subfamily. Its linear, double-stranded DNA genome of about 145 kb shows homologies to human herpesvirus 6 (HHV-6) and cytomegalovirus (CMV). Mature HHV-7 particles measure 170 nm in diameter, with nucleocapsids of 90 to 95 nm and a tegument of approximately 30 nm [ 2 ].
Background: Human herpesvirus-7 (HHV-7) is a newly discovered virus and very little is known about its prevalence, biologic, immunologic and molecular biology aspect. Besides the HHV-7 etiologic role in a few cases of exanthem subitum, its association with other diseases has not been reported. Objectives: To review what is currently known about ...
