Chickenpox (also called varicella) is a common childhood disease. It is usually mild, but it can be serious, especially in young infants and adults.

• The chickenpox virus can be spread from person to person through the air, or by contact with fluid from chickenpox blisters.
  
• It causes a rash, itching, fever, and tiredness.
  
• It can lead to severe skin infection, scars, pneumonia, brain damage, or death.
  
• A person who has had chickenpox can get a painful rash called shingles years later.
  
• About 12,000 people are hospitalized for chickenpox each year in the United States.
  
• About 100 people die each year in the United States as a result of chickenpox.
  

Chickenpox vaccine can prevent chickenpox.

Most people who get chickenpox vaccine will not get chickenpox. But if someone who has been vaccinated does get chickenpox, it is usually very mild. They will have fewer spots, are less likely to have a fever, and will recover faster.
