How chickenpox spreads

You can catch chickenpox by being in the same room as someone who has it, or touching clothes or bedding that have fluid from chickenpox blisters on them.

Chickenpox is infectious from 1 to 2 days before the rash appears until after the blisters have all crusted over.

If your child has chickenpox call their school or creche so that they can inform other parents.

Keep children with chickenpox away from:

  • pregnant women
  • people who have serious health conditions
  • babies
  • childcare facilities like creches and childminders
  • school
  • airplanes

Wait until all lesions have crusted over.

If you have had chickenpox before you are very unlikely to get it again
