What Increases Your Risk
You are at risk for
chickenpox if you have not had chickenpox or the
vaccine and you:
- Live with someone who has
chickenpox.
- Work or play indoors for more than 1 hour with someone
who has chickenpox.
- Are in the hospital and share a room with
someone who later develops chickenpox or are cared for by a staff member who
later develops chickenpox.
- Have an
impaired immune system.
Your risk of getting chickenpox is especially high if you
are exposed to a household member with chickenpox, because of the close
contact. In addition, you may develop a more severe case than the person who
infected you. Chickenpox is most contagious from 1 to 2 days before the rash
appears until the blisters have dried and formed crusts.
Some
people also are at increased risk of developing
complications from chickenpox, such as newborns,
teenagers, adults—especially pregnant women—and those with impaired immune
systems.
After you have had chickenpox or the vaccine, you become
immune to the virus. It is possible that you may have
a slight reaction after reexposure, such as a few spots and a slight fever. But
you are not likely toget chickenpox more than once.
