Flu

Flu will often get better on its own, but it can make some people seriously ill. It's important to get the flu vaccine if you're advised to.

Check if you have flu

Flu symptoms come on very quickly and can include:

a sudden high temperature
an aching body
feeling tired or exhausted
a dry cough
a sore throat
a headache
difficulty sleeping
loss of appetite
diarrhoea or tummy pain
feeling sick and being sick

The symptoms are similar for children, but they can also get pain in their ear and appear less active.

Telling the difference between cold and flu

Cold and flu symptoms are similar, but flu tends to be more severe.

Differences between cold and flu.
Flu	Cold
Appears quickly within a few hours	Appears gradually
Affects more than just your nose and throat	Affects mainly your nose and throat
Makes you feel exhausted and too unwell to carry on as normal	Makes you feel unwell, but you still feel well enough to do your normal activities

How to treat flu yourself

If you have flu, there are some things you can do to help get better more quickly.

Do

rest and sleep
keep warm
take paracetamol or ibuprofen to lower your temperature and treat aches and pains
drink plenty of water to avoid dehydration (your pee should be light yellow or clear)

A pharmacist can help with flu

A pharmacist can give treatment advice and recommend flu remedies.

Do not take paracetamol and flu remedies that contain paracetamol at the same time as it's easy to take more than the recommended dose.

How to avoid spreading the flu

Flu is very infectious and easily spread to other people. You're more likely to give it to others in the first 5 days.

Flu is spread by germs from coughs and sneezes, which can live on hands and surfaces for 24 hours.

To reduce the risk of spreading flu:

wash your hands often with warm water and soap
cover your mouth and nose with a tissue when you cough or sneeze
bin used tissues as quickly as possible

Try to stay at home and avoid contact with other people if you have a high temperature or you do not feel well enough to do your normal activities.

How to get a flu vaccine

Flu vaccines are safe and effective. They're offered every year on the NHS to help protect people at risk of flu and its complications.

The best time to have a flu vaccine is in the autumn before flu starts spreading. But you can get vaccinated later.

Adults who can have a flu vaccine

A flu vaccine is given to people who:

are 50 and over (including those who will be 50 by 31 March 2023)
have certain health conditions
are pregnant
are in long-stay residential care
receive a carer's allowance, or are the main carer for an older or disabled person who may be at risk if you get sick
live with someone who is more likely to get a severe infection due to a weakened immune system, such as someone living with HIV, someone who has had a transplant, or is having certain treatments for cancer, lupus or rheumatoid arthritis

Children who can have a flu vaccine

The children's nasal spray flu vaccine is given to:

children aged 2 or 3 on 31 August 2022 (born between 1 September 2018 and 31 August 2020)
all primary school children
some secondary school children
children aged 2 to 17 with certain health conditions

Babies and children aged 6 months to 2 years with certain health conditions will be offered a flu vaccine injection instead of the nasal spray.

Where to get a flu vaccine

You can have an NHS flu vaccine at:

your GP surgery
a pharmacy offering the service (if you're aged 18 or over)
some maternity services if you're pregnant

Sometimes, you may be offered a flu vaccine at a hospital appointment.

School-aged children will be offered a vaccine at school or a community clinic.

Important

Due to high demand for a flu vaccine, there may be some delays getting a vaccination appointment. Your GP surgery or pharmacy should be able to tell you when more appointments are available.
