Influenza, or flu, is caused by viruses. The symptoms can be similar to a cold but begin much faster and affect the whole body. Usually with flu you are too tired to carry on with your normal activities. Flu can be more harmful for some people, see below for more details.
The symptoms of flu can include:
High temperature (favour)
Shivering
Aching in the limbs
Severe headache
Persistent dry cough
Sore throat
A loss of appetite, diarrhoea and sickness are also experienced by some people.
You can treat the symptoms of flu yourself. Stay hydrated and rest. Painkillers such as paracetamol or ibuprofen will help lower your temperature and help with headaches and aching. It is also important to rest and sleep as well as keep warm. Antibiotics are not required for flu. If in doubt about which remedies are suitable for you then ask your pharmacist.
Some people are at higher risk when they get the flu.
You are over 65 years of age
You have a long term medical condition including: diabetes, lung disease, asthma, heart disease, kidney or liver disease, brain or nerve disorders, a weakened immune system
Or, if your symptoms do not improve after 7 days.
For patients at greater risk of complications from the flu, annual vaccinations are recommended. The NHS in the UK provides free vaccinations all adults over 50, adults with certain health conditions and for pregnant females. More detail on who is eligible for flu vaccinations can be found on the NHS website.
