Clinical Overview of Chickenpox (Varicella)
Cause
Varicella is highly caused by varicella-zoster virus (VZV), which is a DNA virus that is a member of the herpesvirus group. Primary infection with VZV causes varicella.
After the primary infection, VZV stays in the body (in the sensory nerve ganglia) as a latent infection. Reactivation of latent infection causes herpes zoster (shingles).

Who is at risk
People at risk for severe varicella include:
- Immunocompromised people without evidence of immunity to varicella.
- Pregnant women without evidence of immunity to varicella.
- Newborns whose mothers have varicella from 5 days before to 2 days after delivery.
- Premature babies exposed to varicella or herpes zoster.

Incubation period
The average incubation period for varicella is 14 to 16 days after exposure to a varicella or a herpes zoster rash.
It takes from 10 to 21 days after exposure to the virus for someone to develop varicella.
