The symptoms of coronavirus are like flu symptoms. The main difference is that you usually do not have shortness of breath when you have the flu.
Flu (influenza) is a severe infection caused by a virus. The flu virus infects your lungs and upper airways.
Flu is unpredictable. If you are young and healthy, you will usually feel unwell for a week but, you will not need to see your GP. Most flu can be treated at home.
Antibiotics do not work on flu. Getting lots of rest and drinking plenty of liquids will make you feel better.
Most people who think they have the flu usually just have a cold.
The real flu tends to happen during the winter. It usually spreads between October and April.
Some people are at risk of the serious complications of flu.
People at risk of complications include:
- people aged 65 and over
- pregnant women
- people with a long term medical condition
You can see a list of other at-risk groups here.
If you have flu and you are at risk of the complications of flu, you should contact your GP. You may need special anti-viral medicines. These work best if started within 48 hours of flu symptoms.
Flu symptoms come on very quickly and you get muscle aches and a high fever. Headache is very common. You will feel extremely weak and may find it hard to even get out of bed. After a few days, you may develop a cough.
Flu symptoms can also include:
- sore throat
- difficulty sleeping
- loss of appetite
- diarrhoea or tummy pain
- nausea and vomiting
The symptoms are similar for children. But they can also get pain in their ear and may be less active than usual.
It is useful to know the difference between a cold and the flu.

Symptoms of a cold are generally mild compared to flu.
For most people, flu is just a bad experience. But for others, it can lead to more serious illness. Some complications of flu can be life threatening.
