	Herpes simplex type 2 varicella-zoster virus	Disseminated vesicular rash at acquisition (chicken pox): localized vesicular rash with reactivation(zoster).
Subfamily betavirinae	Cytomegalovirus	Mononucleosi-like illness in healthy adults; Fever, pneumonia, and Hepatitis in immunocompromised adults.
	Human herpes virus 6	Acute febrile illness sometimes with rash (roseola infantum),
	Human herpes virus 7	May cause febrile illness sometimes with rash ( roseola-like).
Subfamily gammavirinae	Epstein-Bar virus	mononucleosis, lymphoma, nasopahryngeal carcinoma and hodgkins disease.
