Background
Microbiology
- A family of double-stranded DNA viruses that cause disease in humans
- The human herpesviruses are further subdivided into three subfamilies
- Also remember Macacine alphaherpesvirus 1
| Subfamily | Species | Reservoir | Transmission | Clinical Associations |
|---|---|---|---|---|
| Alphaherpesvirinae | HSV-1 (HHV-1) | Sensory ganglia | Saliva, skin lesions, vertical transmission | |
| HSV-2 (HHV-2) | Skin lesions, sexual contact, vertical transmission | |||
| VZV (HHV-3) | Skin lesions, respiratory droplets, vertical transmission | |||
| Betaherpesvirinae | CMV (HHV-5) | Myeloid progenitors | Saliva, respiratory droplets, vertical transmission | |
| Roseolavirus (HHV-6a and -6b) | Myeloid progenitors | Saliva | ||
| Roseolavirus (HHV-7) | CD4 T cells | Saliva | ||
| Gammaherpesvirinae | EBV (HHV-4) | B lymphocytes | Saliva | Various hematologic malignancies |
| KSHV (HHV-8) | Saliva, sexual contact | HIV, Kaposi sarcoma |
Epidemiology
- Transmitted human-to-human through saliva, skin lesions, respiratory droplets, in utero, or intrapartum
- Except HSV-2 and HHV-8, these viruses are incredibly common in modern human populations
Management
- Typically respond to antivirals, including acyclovir, valacyclovir, ganciclovir, valganciclovir, and foscarnet
