Fever / High Temperature

Fever is extremely common in children and usually suggests that your child has an infection. Your child has a fever if their temperature is over 38°C( 100.4 F). Most children recover quickly with minimal or no treatment. Useful facts regarding fever include:

Viral  Infections:
  • Viral infections are far more common than bacterial infections.
  • Symptoms such as runny nose, cough, wheeze, sore throat, red eyes and diarrhoea are more suggestive of a viral infection than a bacterial infection. If a number of people are unwell in the same household, this also suggests a viral infection (because viral infections are easily spread).
  • Viral infections tend to get better on their own and do not need treatment with antibiotics. Antibiotics may actually cause side effects such as rash and diarrhoea and can increase the risk of them developing antibiotic resistance.
Immunisations

Fever is common in babies up to 48 hours after receiving immunisations.

It is okay to give paracetamol after Men B vaccine ( 8 week vaccination) without seeking medical advise if your baby is otherwise well

Over dressing

Infants, especially newborns may get warm if they are over dressed, wrapped in a blanket or in a hot environment because they do not regulate their body temperature as well as older kids.  But because fevers in newborns can be a sign of serious infection, any infant less than 3 months who has fever must be checked by a doctor.

Fits with fever

Sometimes children with fever can have a fit. This is called a febrile convulsion and most commonly occurs in children aged between 6 months to 6 years.

Most of the time, the fit stopped by themselves and last for less than 5 minutes.  Call 999 if fit lasting more than 5 minutes.  In most cases there are no long-term effects if self-resolving.

Most children that have a febrile fit to not go on to develop epilepsy.

How to take a temperature

It is important to take your child's temperature carefully – you should use a digital thermometer

  • under the armpit for children 5 years and younger
  • in the mouth for children over 5 years .
  • in the ear using a special tympanic thermometer. These allow you to take temperature reading from the ear and are quick but expensive. They can be misleading if you do not put them in the ear correctly which is more likely to happen with babies because the ear holes are too small. Do not use with small babies.

What should you do?

To make your child more comfortable, you may want to lower their temperature using liquid paracetamol/ ibuprofen (e.g. calpol/other brands). This should be given  on the advice of a health professional in babies under 3 months of age  with fever will need medical attention. 

Do not give more than the maximum  recommended daily dose of medicine. However, remember that fever is a normal response that may help the body to fight infection and paracetamol will not get rid of it entirely. Medicines are helpful in reducing the discomfort associated with fever. 

Avoid sponging your baby with tepid water – it doesn’t actually reduce your baby's temperature and may cause hypothermia ( Low body temperature). Babies with fever should not be underdressed or overwrapped. 

Encourage them to drink plenty of feeds.

Paracetamol 

There are different types of paracetamol for children of different ages including 2 different strengths of syrup - infant and Six plus. Always read the dose instructions carefully. You must wait at least 4 hours between doses. Do not give more than 4 doses in 24 hours. 

Ibuprofen

Ibuprofen is available in syrup and tablet form. Ibuprofen is not suitable for some children. If you are unsure whether your child can take ibuprofen, check with your pharmacist or doctor. Always read the dose instructions carefully. Don't give ibuprofen if your child has not had a wee in the last 12 hours. You must wait at least 6 hours between doses. Do not give more than 3 doses in 24 hours. 

  • Paracetamol and ibuprofen can be given together at the same time, although it is often best to see how your child responds to one medicine first before giving the other medicine. Take care not give more than the maximum daily dose of either medication. 
  • It can take 30 minutes for your child’s temperature to start to fall and for your child to start to feel better after taking paracetamol or ibuprofen. 

Further information on how to give these medicines to your child can be found at medicinesforchildren.org.uk 

  • Encourage them to drink plenty of fluids
  • If a rash appears, do the glass test

How long will your child’s symptoms last?

  • Fever caused by a viral infection tends to improve within 2 to 3 days
  • If your child’s fever lasts for more than 5 days, get them seen by your GP

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.
