People with chickenpox get an itchy rash or spots on their skin. The spots are like small water blisters. Some people have only a few blisters. Others can have as many as 500. These blisters dry up and form scabs in 4 or 5 days.
Chickenpox spreads very quickly.
You can get chickenpox if you touch a blister, or the liquid from a blister. You can also get chickenpox if you touch the spit of a person who has chickenpox. The virus can get into your nose or mouth and make you sick also. It can also spread through the air, from someone with chickenpox who is coughing or sneezing. A pregnant woman with chickenpox can pass it on to her baby before birth.
