Coronavirus (COVID-19) can make anyone seriously ill. But for some people, the risk is higher.

There are 2 levels of higher risk:

People at high risk (clinically extremely vulnerable)

You may be at high risk from coronavirus if you:

have had an organ transplant
are having chemotherapy or antibody treatment for cancer, including immunotherapy
are having an intense course of radiotherapy (radical radiotherapy) for lung cancer
are having targeted cancer treatments that can affect the immune system (such as protein kinase inhibitors or PARP inhibitors)
have blood or bone marrow cancer (such as leukaemia, lymphoma or myeloma)
have had a bone marrow or stem cell transplant in the past 6 months, or are still taking immunosuppressant medicine
have been told by a doctor you have a severe lung condition (such as cystic fibrosis, severe asthma or severe COPD)
have a condition that means you have a very high risk of getting infections (such as SCID or sickle cell)
are taking medicine that makes you much more likely to get infections (such as high doses of steroids or immunosuppressant medicine)
have a serious heart condition and are pregnant
have a problem with your spleen or your spleen has been removed (splenectomy)
are an adult with Down's syndrome
are an adult who is having dialysis or has severe (stage 5) long-term kidney disease
have been classed as clinically extremely vulnerable, based on clinical judgement and an assessment of your needs

If you're at high risk from coronavirus, you should have received a letter from the NHS.

Speak to your GP or hospital care team if you have not been contacted and think you should have been.

If you're at high risk from coronavirus, there are things you can do to help keep yourself safe.

People at moderate risk (clinically vulnerable)

People at moderate risk from coronavirus include people who:

are 70 or older
have a lung condition that's not severe (such as asthma, COPD, emphysema or bronchitis)
have heart disease (such as heart failure)
have diabetes
have chronic kidney disease
have liver disease (such as hepatitis)
have a condition affecting the brain or nerves (such as Parkinson's disease, motor neurone disease, multiple sclerosis or cerebral palsy)
have a condition that means they have a high risk of getting infections
are taking medicine that can affect the immune system (such as low doses of steroids)
are very obese (a BMI of 40 or above)
are pregnant

Unlike people at high risk, you will not get a letter from the NHS.

If you're at moderate risk from coronavirus, the advice for you depends on the rules where you live.

The advice is based on the level of risk in your area. These levels are called local restriction tiers.
