| ==Overview==
| |
| [[Chickenpox]] is caused by the [[varicella-zoster virus]] (VZV), also known as human herpes virus 3 (HHV-3), one of the eight [[herpesviridae|herpes viruses]] known to affect humans. | |
| | |
| ==Causes==
| |
| About 1 in 10 adults will experience [[shingles]] when the [[virus]] re-emerges during a period of [[stress]].
| |
| Most cases of [[chickenpox]] occur in children younger than ten. The disease is usually mild, although serious complications sometimes occur. Adults and older children usually get sicker than younger children do.
| |
| Children under one year of age whose mothers have had [[chickenpox]] are not very likely to catch it. If they do, they often have mild cases because they retain partial [[immunity]] from their mothers' blood. Children under one year of age whose mothers have not had [[chickenpox]], or whose inborn [[immunity]] has already waned, can get severe [[chickenpox]].
