Chickenpox is normally a mild disease. But it can be serious and can lead to complications, especially in these high-risk groups:
- Newborns and infants
- Teenagers
- Adults
- Pregnant women
- People whose immune systems are impaired by another disease or condition
- People who are taking steroid medications for another disease or condition, such as children with asthma
The most common complication of chickenpox is a bacterial infection of the skin. Chickenpox may also lead to pneumonia or an inflammation of the brain (encephalitis), both of which can be very serious if not treated.
Anyone who has had chickenpox as a child is also at risk for a latent illness called shingles.
After an infection, some of the varicella-zoster virus may remain in your nerve cells. Many years later, the virus can reactivate and resurface as shingles — a painful band of short-lived blisters.
About one in ten adults who've had chickenpox experience shingles.
The virus is more likely to reappear in older adults and people with weakened immune systems.
Shingles can lead to its own complication — a condition in which the pain of shingles persists long after the blisters disappear. This complication, called postherpetic neuralgia, can be severe.
Other complications of chickenpox affect pregnant women.
Chickenpox early on in pregnancy can result in a variety of problems in a newborn, including low birth weight and birth defects, such as limb abnormalities.
A greater threat to a baby occurs when the mother develops chickenpox in the week before birth. Then it can cause a serious, life-threatening infection in a newborn.
If you're pregnant and aren't immune to chickenpox, talk to your doctor about the risks to you and your unborn child.
