COVID-19 (coronavirus) can make anyone seriously ill. But for some people, the risk is higher.
If you are at higher risk from COVID-19, follow the advice below on how to protect yourself. Use your own judgement to stay safe in public and crowded places.
People at higher risk
People over 65 are at the highest risk of serious illness from COVID-19 if they have not been vaccinated.
Serious illness means that you may need to go to hospital, an intensive care unit (ICU), or be put on a ventilator to help you breathe. There is also a risk of death.
Having a weak immune system (immunocompromised) puts you at higher risk. If you have a weak immune system, you should have had your first round of vaccination, an additional dose of the COVID-19 vaccine and a booster dose.
You are also at higher risk from COVID-19 if you have certain medical conditions.
There are 2 levels of higher risk:
Very high risk groups (extremely vulnerable)
The list of people in very high risk groups include people who:
- have Down Syndrome
- have cancer and are being treated with chemotherapy or similar drugs other than hormone therapy
- have lung or head and neck cancer and are having radical surgery or radiotherapy
- are having radical radiotherapy for lung cancer or head and neck cancer
- are having certain complex cancer surgery, for example, surgery for lung cancer, head and neck cancer or oesophageal cancer
- have advanced cancer or cancer that has spread to another part of the body
- are on dialysis or have end-stage kidney disease and an eGFR less than 15
- have a condition affecting the brains or nerves that has significantly affected your ability to breathe, meaning you require non-invasive ventilation (such as motor neurone disease or spinal muscular atrophy)
- have unstable or severe cystic fibrosis, including people waiting for a transplant
- have severe respiratory conditions including Alpha-1 antitrypsin deficiency, severe asthma, pulmonary fibrosis, lung fibrosis, interstitial lung disease and severe COPD
- have uncontrolled diabetes
- have had an organ transplant or are waiting for a transplant
- have had a bone marrow or stem cell transplant in the last 12 months, or are waiting for a transplant
- have a rare condition that means you have a very high risk of getting infections (such as APECED or errors in the interferon pathway)
- sickle cell disease
- have been treated with drugs such as Rituximab, Cyclophosphamide, Alemtuzumab, Cladribine or Ocrelizumab in the last 6 months
- have certain inherited metabolic disorders (such as Maple Syrup Urine Disease)
- have obesity with a body mass index (BMI) greater than 40
High risk groups
The list of people in high risk groups includes people who:
- are age 55 or older and not fully boosted
- have a learning disability other than Down Syndrome
- are being treated for cancer but are not very high risk
- have been treated in the past 5 years for a cancer of the blood or bone marrow (such as leukaemia, lymphoma or myeloma)
- have been treated in the past 1 year for a cancer that did not start in the blood or bone marrow
- have chronic heart disease (such as heart failure)
- have chronic kidney disease with an eGFR below 30ml a minute
- have chronic liver disease (such as cirrhosis or fibrosis)
- have a condition affecting the brain or nerves (such as Parkinson's disease or cerebral palsy) that affects their breathing or ability to protect or clear their airway
- have clinically stable cystic fibrosis
- have a serious lung condition but are not at very high risk, for example, moderate COPD, severe asthma, emphysema or bronchitis
- have diabetes
- are taking medicine that makes you much more likely to get infections (such as high doses of steroids)
- have a condition that means you have a high risk of getting infections (such as HIV, lupus or scleroderma)
- have an inherited metabolic disorder but are not very high risk
- have obesity with a body mass index (BMI) between 35 and 40
- have a severe mental illness (such as schizophrenia, bipolar disorder, severe depression)
If you have COVID-19 symptoms
Get a PCR test if you have COVID-19 symptoms and you have a:
- high risk medical condition
- weak immune system (immunocompromised)
Urgent advice: Phone your GP if:
- you have a very weak immune system (immunocompromised) and have symptoms of COVID-19
You may be recommended treatment for COVID-19.
Treatment for COVID-19
There are new medicines for early treatment of some people with COVID-19. Most people who catch COVID don’t need this treatment. It’s available to people who are at the highest risk of serious illness or death from COVID-19.
How to protect yourself if you're at high risk
Getting vaccinated is the most important thing you can do to avoid serious COVID-19 illness. Talk to your GP or hospital care team if you have any questions about vaccination.
- try to avoid crowded indoor spaces, if possible
- wear a medical or respirator face mask in indoor or outdoor crowded places, including public transport
- wash or sanitise your hands often
- continue to use the healthcare services you need - ask or remind healthcare workers about precautions if needed
- keep active and look after your general health - this will improve your chance of recovery if you get COVID-19
- keep 2 metres away from other people
- do not have contact with anyone who has COVID-19 or has symptoms of COVID-19
Going out is good for your health and wellbeing. The risk of catching COVID-19 is low if you keep away from other people.
You can tell people who provide services to you that you need to be extra careful to avoid COVID-19. They will usually try to fit you in at a quiet time and can take extra care to protect you.
If you have an appointment with your GP or at a hospital or clinic, it is important to attend.
You are more likely to be exposed to COVID-19 if you are in a place where there are large numbers of people indoors.
Staying safe at home
Try to keep the number of people who come into your house to visit, work or provide healthcare to a small number of trustworthy people. Then you can feel safe at home and relax there.
Check that anyone who comes to the house is well when they arrive. Make sure they have no symptoms of COVID-19.
Ask them to:
- clean their hands when they arrive
- wear a medical grade or respirator mask
- keep some distance from you whenever possible
What the people you live with should do
It is usually not practical for people living together to avoid contact with each other at home.
Other people you live with can protect you by:
- getting vaccinated and getting their booster dose when it's due
- washing their hands properly when they come into the house
- opening windows to let fresh air into shared spaces
- cleaning objects and surfaces they often touch such as door handles, kettles and phones
If anyone you live with has symptoms of COVID-19, they should self-isolate and avoid contact with you completely.
Stay in touch with friends and family. If you need help for any reason there are places you can go for help.
