Chickenpox
Chickenpox is a very common childhood illness, caused by a virus called varicella.
It starts with red bumps that become small, yellowish blisters affecting the whole body
including the mouth and genitals (which can be very painful). They then open before
scabbing over. These are very itchy and can make your child miserable. They may have a
temperature, a cough and a runny nose.
Children are able to pass the virus to others from the day before the rash appears until the
last spot has scabbed over.
Chickenpox rarely needs treatment, unless in a new-born baby, or in a child with a known
weak immune system (for example due to weakened immune system due to anti-cancer
treatment, immunosuppressive treatment or genetic immunodeficiency). If you are not sure
it is chickenpox look at other childhood rashes
Top Tip

Please contact your GP your child's own hospital doctor if:
They are on medicine that affects their immune system (immunosuppressive medication eg chemotherapy, high dose steroids) or are under a month old, they made need treatment straight away.

What can you do to help your child?
Seeing your child unwell with chickenpox can be very distressing for a parent and while there is usually no treatment for the virus itself, there are simple things you can do to make your child more comfortable:
- Regular Paracetamol for temperature/pain
- Antihistamines (eg piriton) can help with itching and aid sleep
- Drink plenty of fluid and try ice lollies if your child is not drinking much
- Calamine lotion/oat milk bath/Sodium bicarbonate bath for itch
- Pat dry after bath rather than rubbing for comfort
- Dress in loose clothes
- Don’t give ibuprofen or aspirin unless advised to by a doctor
- Cut nails/apply hand mittens at night to reduce damage to skin and try to
- Avoid too much scratching if possible
How long does it last?
- Usually the last spot has crusted over by 5-7 days after the rash first appears
- It is highly contagious until spots have dried and scabbed over
- Avoid nursery or school for 5 days from rash onset or until all spots are fully scabbed over
- Avoid contact with new-born babies, people with a weakened immune system and pregnant women until all of their spots have scabbed over. If concerned regarding this contact your GP
The chickenpox vaccine
The chickenpox vaccine is a vaccine used to prevent catching and spreading the disease. It has recently been recommended but is not yet part of the standard vaccine programme but is offered to children who are at increased risk of severe chickenpox infection and to those with a family member at risk of complications. It is also available privately through travel clinics and pharmacies and costs between £120-£200. More information is available at Chickenpox vaccine overview - NHS (www.nhs.uk)
How is chickenpox spread?
Children and adults can get chickenpox, but it is more common in children. Chickenpox is highly contagious, which means it is very easy to catch. It can be spread by having direct contact with the person who has chickenpox, especially by touching the liquid from the blisters. Chickenpox is also spread by the fluids that are coughed or sneezed into the air.
If your child has chickenpox, they are infectious to others from one to two days before the rash first appears up until the last blisters have dried up. Some members of the family may need to stay away from the child during this infectious stage. Anyone taking long-term oral steroids or who is immunocompromised (has a weakened immune system e.g. due to chemotherapy), pregnant women or babies under three months should see a GP if they could have been exposed to chickenpox, as they may need treatment to prevent the virus.
Children with chickenpox should not go to child care, kindergarten or school until the last blister has dried, (see our should my child go to school page). A dry blister scab is not infectious. You should tell the school if your child gets chickenpox, as there may be other children who need to be immunised or treated.
Key points to remember
- Chickenpox is very easy to catch, and is infectious for one to two days before the rash starts up until the last blister has dried.
- The rash usually starts between 10 to 21 days after the first exposure to chickenpox
- Â Antibiotics will not cure chickenpox.
Common questions our doctors are asked
Will my child’s chickenpox blisters scar?
Chickenpox sometimes causes pockmark scars on the skin. Regular chicken pox blisters do not scar, but if they are scratched or become infected, they are more likely to leave permanent marks on the skin.
How can I stop my child scratching their rash?
There are many medications and creams that you can buy from your local pharmacy to help with the itching – ask your pharmacist for advice. Young children and babies might need to wear mittens to help prevent them from scratching.
What can I do about the blisters inside my child’s mouth?
Unfortunately, there isn’t much you can do to help the blisters. Try giving your child paracetamol or ibuprofen to relieve the pain. If your child is in so much pain from mouth blisters that they are not drinking, they will need to be admitted to hospital to prevent dehydration.
What are the serious complications of chickenpox?
One in 5000 people who catch chickenpox will develop a brain inflammation called encephalitis, and three in 100,000 will die. These complications are very rare and most children make a full recovery.
Can my child be immunised against chickenpox?
You can get the chickenpox vaccine on the NHS if there's a risk of harming someone with a weakened immune system if you spread the virus to them.
For example, a child can be vaccinated if 1 of their parents is having chemotherapy.
You can also pay for the vaccine at some private clinics or travel clinics. It costs between £120 and £200.
Where should you seek help?
- If it is non-urgent, speak to your local pharmacist or health visitor.
- If your child has any of the above features in amber, urgently see your GP. For an urgent out-of-hours GP appointment, call NHS 111.
- You should only call 999 or go your nearest A&E department in critical or life threatening situations or if your child is showing any of the signs in the red section above.
A&E departments provide vital care for life-threatening emergencies, such as loss of consciousness, suspected heart attacks, breathing difficulties, or severe bleeding that cannot be stopped. If you’re not sure it’s an emergency, call 111 for advice.
