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 ( i.e. 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 here.
Before or after the rash appears, you might also get:
Chickenpox is very itchy and can make children feel miserable, even if they do not have many spots.
The chickenpox spots look the same on children and adults. But adults usually have a high temperature for longer and more spots than children.
It's possible to get chickenpox more than once, but it's unusual.
Check other rashes in children
You'll need to stay away from school, nursery or work until all the spots have formed a scab. This is usually 5 days after the spots appeared.
drink plenty of fluid (try ice lollies if your child is not drinking) to avoid dehydration
take paracetamol eg Calpol to help with pain and discomfort
cut your child's fingernails and put socks on their hands at night to stop them scratching
use cooling creams or gels from a pharmacy
speak to a pharmacist about using antihistamine medicine to help itching
bathe in cool water and pat the skin dry (do not rub)
dress in loose clothes
do not use ibuprofen unless advised to do so by a doctor, as it may cause serious skin infections
do not give aspirin to children under 16
do not go near newborn babies, people who are pregnant and people with a weakened immune system, as chickenpox can be dangerous for them
do not scratch the spots, as scratching can cause scarring
Tell the receptionist you think it might be chickenpox before going in to a GP surgery.
Some people may be able to take medicine to prevent complications. It needs to be started within 24 hours of the spots appearing.
111 will tell you what to do. They can arrange a phone call from a nurse or doctor if you need one.
Go to 111.nhs.uk or call 111.
You can catch chickenpox by being in the same room as someone with it. It's also spread by touching things that have fluid from the blisters on them.
You can spread chickenpox to other people from 2 days before your spots appear until they have all formed scabs – usually 5 days after your spots appeared.
The spots start appearing around 1 to 3 weeks after you caught chickenpox.
Most people get chickenpox during childhood, so it's rare to get chickenpox when you're pregnant.
If you do get chickenpox when you're pregnant, there's a small risk of your baby being very ill when it's born.
Go to 111.nhs.uk or call 111 if you have not had chickenpox before and you've been near someone with it.
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.
You cannot catch shingles from someone with chickenpox.
You can catch chickenpox from someone with shingles if you have not had chickenpox before.
When you get chickenpox, the virus stays in your body. The virus can be triggered again if your immune system is weak. This causes shingles.
This can happen because of stress, certain conditions, or treatments like chemotherapy.

It is not part of the standard vaccine programme but is offered to childrenwho 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 here.
You can treat your child's very minor illnesses and injuries at home.
Some illnesses can be treated in your own home with support and advice from the services listed when required, using the recommended medicines and getting plenty of rest.
Children can recover from illness quickly but also can become more poorly quickly; it is important to seek further advice if a child's condition gets worse.

School nurses care for children and young people, aged 5-19, and their families, to ensure their health needs are supported within their school and community. They work closely with education staff and other agencies to support parents, carers and the children and young people, with physical and/or emotional health needs.
Contacting the School Nurse
Primary and secondary schools have an allocated school nurse – telephone your child’s school to ask for the contact details of your named school nurse.
There is also a specialist nurse who works with families who choose to educate their children at home.
Before your child starts school your health visitor will meet with the school nursing team to transfer their care to the school nursing service. The school nursing team consists of a school nursing lead, specialist public health practitioners and school health staff nurses.
They all have a role in preventing disease and promoting health and wellbeing, by:-
Each member of the team has links with many other professionals who also work with children including community paediatricians, child and adolescent mental health teams, health visitors and speech and language therapists. The school health nursing service also forms part of the multi-agency services for children, young people and families where there are child protection or safeguarding issues.
GPs assess, treat and manage a whole range of health problems. They also provide health education, give vaccinations and carry out simple surgical procedures. Your GP will arrange a referral to a hospital specialist should you need it.
