If your child has chickenpox, Public Health England recommends that you inform their school or nursery, and keep them at home for five days.
If you have chickenpox, stay off work and at home until you’re no longer infectious, which is until the last blister has burst and crusted over. This usually happens five or six days after the rash begins.
It is a good idea for anyone who has chickenpox to avoid contact with:
If you or your child have recently been exposed to the chickenpox virus, you may not be able to visit friends or relatives in hospital. Telephone the ward to check first.
If you or your child have chickenpox, you may not be allowed to fly until six days after the last spot has appeared.
You and your child should be safe to fly once you’re past the infectious stage and all of the blisters have crusted over. However, it’s best to check the policy of your airline first. Inform the airline as soon as chickenpox is diagnosed.
It is also important to let your travel insurer know if you or your child has chickenpox. You need to make sure that you’ll be covered if you have to delay or cancel your holiday, or if you need to extend your stay until your child is well enough to fly home.
Chickenpox can sometimes be spread through contact with objects that have been contaminated with the virus, such as children’s toys, bedding or clothing.
If someone in your household has chickenpox, you can help stop the virus spreading by wiping any objects or surfaces with a sterilising solution and making sure that any infected clothing or bedding is washed regularly.
There is a chickenpox vaccine that is used to protect people who are most at risk of a serious chickenpox infection or of passing the infection on to someone who is at risk.
People who may be considered for chickenpox vaccination include:
The vaccine is not suitable for pregnant women. Avoid getting pregnant for three months after having the vaccine. The vaccine is also not suitable for people with weakened immune systems.
The recommended two doses of the vaccine is estimated to offer 98% protection from chickenpox in children and 75% protection in adolescents and adults.
So it may be possible to develop the infection after vaccination.
