Chickenpox Complications

While most cases of Chickenpox are mild and resolve on their own without complications, there are some potential complications that can arise, especially in certain groups of people.

Possible Complications of Chickenpox

Bacterial Infections

  • Scratching Chickenpox blisters can lead to bacterial infections, such as impetigo or cellulitis.


  • In rare cases, Chickenpox can lead to pneumonia, which can be life-threatening, especially in adults and people with weakened immune systems.


  • Chickenpox can cause inflammation of the brain, called encephalitis, which can lead to seizures, coma, and even death in rare cases.

Reye’s Syndrome

  • This is a rare but serious complication that can occur in children who take Aspirin during a viral illness. It can cause brain and liver damage and can be fatal.


  • After a person recovers from Chickenpox, the virus remains dormant in the body and can reactivate later in life, causing a painful condition called shingles.
