Who is at Risk from Chickenpox?

Chickenpox is a common childhood infection. In most cases, it’s mild and complications are rare. Almost all children develop immunity to chickenpox after infection, so they usually only catch it once. The disease can be more severe in adults.

Certain groups of people, however, are at greater risk of serious complications from chickenpox. These include:

People who have weakened immune systems through an illness such as HIV or through treatment such as chemotherapy.

Pregnant women. Chickenpox can be very serious for an unborn baby when a pregnant woman catches the infection. It can cause a range of serious birth defects, as well as severe disease in the baby when it is born.
