Herpesviridae is an infection caused by the herpes simplex virus.It affects the skin and nervous system and produces small temporary (but sometimes painful) blisters on the skin and mucous membranes.
Viral Structure & Classification
It is a Family of double-stranded DNA viruses that consist of a spherical virion having the DNA packaged in a liquid crystalline array in a central core surrounded by an icosahedral capsid, an amorphous tegument, and an envelope consisting of a lipid bilayer closely associated with the amorphous protein layer.
Herpesviridae Subfamilies
Alphaherpesvirinae. Members of this subfamily are neurotropic (infect nervous system tissue), have a short reproductive cycle (~18 hr.) with efficient cell destruction and variable host range.
Common name Scientific name Disease they cause
Herpes simplex virus 1 Human herpesvirus 1 facial, labial and ocular lesions
Herpes simplex virus 2 Human herpesvirus 2 genital lesions
Varicella-zoster virus Human herpesvirus 3 chickenpox and shingles
Chicken Pox Facial lesion
genital lesion
Betaherpesvirinae. Members are lymphotropic, have a long reproductive cycle, restricted host range and infected cells become enlarged (cytomegalo).
Common name
- Human cytomegalovirus
- Human herpesvirus 5
Disease they cause
- infectious mononucleosis
effects of mononucleosis
Common name
- (no common names)
- Human herpesvirus 6 & 7
- mild early childhood roseola
Gammaherpesvirinae. These herpesviruses are also lymphotropic and specific for either T or B lymphocytes.
Common name
- Epstein Barr virus
Scientific name
- Human herpesvirus 4
Disease they cause
- cofactor in human cancers
I believe the picture of the african child is the symptom of African Burkitt's lymphoma caused by EBV (HHV-4), which is different manifestation resulting from the same virus responsible for the mononucleosis, and not by the CMV (HHV-5). The term cytomegalo refers to the microscopic feature rather than gross feature, and despite the name the symptoms are often subclinical. So, the "disease they cause" and the picture of the child should be moved to the gammaherpesviridae, HHV-4 section.
