A. Not usually. Children typically build up a lifelong immunity to chicken pox after getting an infection and don't get it again.
There are some situations in which a child might get a second case of chicken pox though, including:
- getting his first case of chicken pox when they were very young, especially if they were younger than 6 months old
- having a mild or subclinical infection the first time
- developing a problem with his immune system
Fortunately, with the rise in use of the chicken pox vaccine, the incidence of first and second cases of chicken pox is much less common these days.
