What to do if you feel unwell

If you’re feeling unwell and wondering if your symptoms are due to COVID-19, or if you or someone in your family has COVID-19, this page includes the latest information on what to do.

The symptoms of COVID-19

The three key symptoms of COVID-19 are:

  • A high temperature – you feel hot to touch on your chest or back
  • A new, continuous cough – coughing a lot for over a hour, or 3 coughing episodes in 24 hours (if you usually have a cough, it may be worse)
  • Loss or change to your sense of smell or taste – you cannot smell or taste anything, or things smell or taste different to normal

If you have any of these symptoms, you should self-isolate for 10 days and request an antigen test. Do not wait. Ask for the test as soon as you have symptoms. You need to be tested within the first 5 days of having symptoms in Scotland and Wales, and if you live in Scotland you should still book a test after 5 days if advised to do so. On days 1 to 4, you can get tested at a site or at home. If you’re ordering a home test kit on day 4, do it by 3pm. On day 5, you need to go to a test site - it’s too late to order a home test kit. You need to be tested within the first 8 days of having symptoms in England and Northern Ireland. On days 1 to 7, you can get tested at a site or at home. If you’re ordering a home test kit on day 7, do it by 3pm. On day 8, you need to go to a test site - it’s too late to order a home test kit.

Other common symptoms of COVID-19 include:

  • Body aches and feeling tired
  • Feeling short of breath
  • Headache
  • A sore throat
  • Runny nose
  • Feeling sick, vomiting and diarrhoea

If your symptoms go on for longer than 10 days

After 10 days, you can stop self-isolating if your symptoms have gone or you only have a cough, or loss or change to your sense of smell or taste, because these symptoms can take a while to go away

You should continue to self-isolate after 10 days if you have any of the following symptoms:

  • Fever
  • Runny nose
  • Sneezing
  • Feeling or being sick
  • Loose or watery poos (diarrhoea)

If you have a fever, runny nose, sneezing or feel sick, self-isolate until your symptoms have gone.

If you are being sick, or have loose or watery poos, continue to self-isolate for 48 hours after your symptoms have gone.

What should you do if you feel unwell

Most cases of COVID-19 can be managed at home with rest, drinking fluids and taking fever reducing medication if appropriate. When unwell it is very important to follow self-isolation guidance so that you don’t spread the infection to others.

Will I get seriously ill?

Around 8 out of 10 people will get a mild form of the illness.1 A small number of people go on to develop difficulty breathing and need to go to hospital.

In those who develop breathlessness, this can happen in the second week of illness.2,3

The people most at risk of getting more serious symptoms are those with other health problems, such as heart disease, diabetes, high blood pressure or long-term breathing problems, such as COPD (chronic obstructive pulmonary disease)

Info for vulnerable individuals

When should I get medical help?

Seek medical attention immediately if you:

  • Feel increasingly breathless or feel short of breath when moving around
  • Feel very weak
  • Lose your appetite
  • Start shaking or shivering
  • Are unable to look after yourself at home due to your symptoms, such as washing yourself or preparing food

You can do this by:

  • Using the NHS 111 online service or calling 111 if you are unable to get help online
  • Getting same day advice from your GP

If you feel extremely unwell to not delay getting help, by calling 999 or going to your nearest A&E.

If you need medical help that is not related to COVID-19, contact your GP service by telephone for advice or check the GP surgery’s website.

Continue self isolating and do not go to A&E, visit your GP surgery or go to a pharmacy as you may spread the infection to others.

How is COVID-19 treated?

Most people with COVID-19 recover without a need for treatment.

In rare and severe cases of COVID-19, treatment includes admission to hospital and care that’s focused on supporting the person through the illness, whilst their immune system works to clear it. Treatments are emerging for patients with severe forms of the disease requiring oxygen.
