How long does chicken pox typically last?

1-2 weeks: Typically chicken pox lasts about a week. However until all the lesions dry up and no longer are contagious could take 2 weeks.

Varicella: Chickenpox can last for three weeks or more. The problem is scarring, this is almost always accompanied by scratching the blisters. If a child is prone to scratching chickenpox, it really helps to have them on an antibiotic during the course of this condition. A physical is needed, too, and vital signs taken for any sign of fever, etc.

Range of issues: The kid with chickenpox has been incubating it in his or her system for 10-21 days by the time it erupts.It erupst in waves of new blisters for a period of up to 6 days and is contagious from 24-48 hours prior to eruption until the last new blister dries.It then takes a week or two for most of the blisrer sites to fade some.The skin may look irregular for a year or more at the site of some lesions.
