How do you catch chickenpox?

Page last updated 21 June 2018

Chickenpox is highly contagious and can be spread by being in close contact with someone who has chickenpox.

  • Skin to skin contact with someone who has chickenpox, specifically from the fluid-filled blisters
  • By breathing in air droplets from a sneeze or cough
  • Infected surfaces that an ill person has touched

As chickenpox and shingles are caused by the same virus, you can also catch chickenpox from people with shingles if you touch or breathe in particles from shingles blisters.

A person with the chickenpox is generally contagious from the beginning of the illness (up to 2 days before the spots appear) until about 5 days after the first spots appear. So long as there are no new blisters or moist crusts on spots, the person will not be contagious even if there are still crusts on the skin. 

You should always practice good health habits to avoid spreading the illness, such as:

  • Avoid contact with people until the spots has healed and you feel better
  • Wash hands regularly
  • Cover your mouth when you cough
