Introduction
Figure 1. Transmission electron micrograph visualization of Human Herpes Virus-6 (HHV-6) on the surface of a human lymphocyte. HHV-6 is the causative agent of roseola, a disease that effects nearly every human infant.
Genomic Structure of HHV-6
Figure 2. Genomic organization of HHV-6B. The asterisk indicates the start of lytic genomic replication. Viral telomeric sequences are indicated by green bars T1 and T2. Open arrows represent protein coding regions.
HHV-6 Replication Cycle
Epidemiology
Pathophysiology of HHV-6 Infection
Figure 4. HHV-6 infection results in roseola, often diagnosed by a characteristic red rash. The roseola rash can form as either raised bumps or can be flat. It is non-contagious and is usually found on the neck, abdomen, back, and trunk, but can also be present on the arms and legs
