Chickenpox, also known as varicella, is a very contagious disease caused by the varicella-zoster virus. It is spread easily through the air by infected people when they sneeze or cough. The disease also spreads through contact with an infected person's chickenpox blisters. Because chickenpox is very contagious, it is possible for people who have never had chickenpox nor been vaccinated against it to become infected just by being in a room with someone who has the disease. However, transient exposure is not likely to result in infection.
