Chickenpox is very easy to catch (it’s highly contagious).
The chickenpox virus spreads through the air (by coughing and sneezing) and by direct contact with mucus, saliva, or liquid from blisters. You can catch the chickenpox virus from touching clothing or other objects that have the blister liquid on them.
The incubation period is the time from when your child comes into contact with a person with chickenpox, to when the first symptoms appear. The incubation period for chickenpox is usually 14 to 16 days but can range from 10 to 21 days.
A child is infectious 1-2 days before they get the rash until all the blisters have dried up. This usually takes 5 to 7 days.
