Overview

• a very high temperature or you feel hot and shivery
• a severe sore throat
• swelling either side of your neck - swollen glands
• extreme tiredness or exhaustion
• tonsilitis that is not getting better

These are glandular fever symptoms.

You do not usually get glandular fever more than once.

What happens at your appointment

Your GP might order a blood test to confirm it's glandular fever and to rule out other illnesses, like tonsillitis. This would test for the Epstein-Barr virus which causes glandular fever.

The GP will not give you antibiotics. Glandular fever is caused by a virus so antibiotics will not work.

Get to A&E or call 999 if you have:

• difficulty swallowing
• difficulty breathing
• extreme tummy pain

How to treat glandular fever yourself

There's no cure for glandular fever – it gets better by itself.

Do

• rest and sleep
• drink plenty of fluids (to avoid dehydration)
• take painkillers like paracetamol or ibuprofen (do not give aspirin to children under 16)

Don’t

• do not drink alcohol – your liver might be weak while you have glandular fever

How long glandular fever lasts

You should feel better within 2 to 3 weeks. Some people might feel extremely tired for months.

Try to gradually increase your activity when your energy starts to come back.

Glandular fever can cause your spleen to swell. For the first month, avoid heavy lifting and sports or activities that might increase your risk of falling, as this may damage your spleen.

How to stop glandular fever spreading

Glandular fever is spread through spit, so you can get it through kissing or by sharing cups or cutlery.

You're infectious for up to 7 weeks before you get symptoms.

You can go back to school or work as soon as you start to feel better.

To prevent glandular fever spreading:

Do

• wash hands regularly
• wash bedding and clothes that may have spit on them

Don't

• do not kiss others (glandular gever is known as the kissing disease)
• do not share cups, cutlery or towels

Glandular fever complications

Most people get better with no problems. But sometimes glandular fever may lead to other illnesses, such as:

• mild liver inflammation (hepatitis), which causes yellowing of the skin and whites of the eyes (jaundice)
• low levels of blood cells called platelets (thrombocytopenia)
• neurological conditions, such as Guillain-Barré syndrome or Bell's palsy
