Overview
Pathophysiology
Transmission of infection
- Virus replicated in the salivary glands and secreted in saliva is the source of infection transmission.
- Intrauterine transmission was suggested by polymerase chain reaction (PCR) positivity of uncultured cord blood mononuclear cells.
Pathogenesis
- The human herpes virus infects the T cells, monocytes-macrophages, epithelial cells, and central nervous system cells resulting in a chronic infection.
- HHV-6 has tropism towards CD4 T cells and replicates in the T cells inducing a lifelong latent infection in humans.
- The pathogenicity of HHV-7 is not well understood.
Genetics
- Chromosomal integration of HHV-6A and HHV-6B is responsible for transmission of infection from the parents to the newboen and is observed in 1% of the population.
