Incubation:
The incubation period for chicken pox is from 7 to 21 days after exposure, with most cases appearing between 14 and 17 days. If, for example, one child in a family breaks out with chicken pox picked up at school, his brothers and sisters probably will exhibit symptoms of chicken pox about 2 weeks later.

Chicken Pox - Varicella
Duration:
Chicken pox usually lasts 7 to 10 days in children, longer in adults.
Contagiousness:
The contagious period for chicken pox begins 2 days before the skin blisters appear and lasts until all the blisters are crusted over. A child with chicken pox should be kept out of school for about 1 week. You don't have to wait until all the scabs fall off.
People with diseases or problems with their immune system should not come in contact with chicken pox. Neither should pregnant women.
