People with Certain Medical Conditions
This information is intended for a general audience. Healthcare professionals should see Underlying Medical Conditions Associated with Higher Risk for Severe COVID-19 for more detailed information.
What You Need to Know
- A person with any of the medical conditions listed below is more likely to get very sick with COVID-19. If you have one of these conditions, talk with your healthcare provider about how best to protect yourself from severe illness from COVID-19.
- The list below does not include all possible conditions that put you at higher risk of severe illness from COVID-19. If you have questions about a condition not included on this list, talk to your healthcare provider about how best to manage your condition and protect yourself from COVID-19.
- If you have symptoms consistent with COVID-19 and you are aged 50 years or older OR are at high risk of getting very sick, you may be eligible for treatment. Contact your healthcare provider and start treatment within the first 5-7 days after you first develop symptoms. You can also visit a Test to Treat location. Treatment can reduce your risk of hospitalization by more than 50% and also reduces the risk of death.
- Staying up to date with COVID-19 vaccines and following preventive measures for COVID-19 are important. This is especially important if you are older or have severe health conditions or more than one health condition, including those on the list below.
- Approved and authorized COVID-19 vaccines are safe and effective.
- Some people who are immunocompromised, or people with weakened immune systems, may get additional doses of COVID-19 vaccine.
Overview
Based on the current evidence, a person with any of the conditions listed below is more likely to get very sick from COVID-19. This means that a person with one or more of these conditions who gets very sick from COVID-19 (has severe illness from COVID-19) is more likely to:
- Be hospitalized
- Need intensive care
- Require a ventilator to help them breathe
- Die
In addition:
- Older adults are at highest risk of getting very sick from COVID-19. More than 81% of COVID-19 deaths occur in people over age 65. The number of deaths among people over age 65 is 97 times higher than the number of deaths among people ages 18-29 years.
- A person’s risk of severe illness from COVID-19 increases as the number of underlying medical conditions they have increases.
- Some people are at increased risk of getting very sick or dying from COVID-19 because of where they live or work, or because they can’t get health care. This includes many people from racial and ethnic minority groups and people with disabilities.
- Studies have shown people from racial and ethnic minority groups are also dying from COVID-19 at younger ages. People in racial and ethnic minority groups are often younger when they develop chronic medical conditions and may be more likely to have more than one medical condition.
- People with disabilities are more likely than those without disabilities to have chronic health conditions, live in shared group (also called “congregate”) settings, and face more barriers in accessing health care. Studies have shown that some people with certain disabilities are more likely to get COVID-19 and have worse outcomes.
Staying up to date with COVID-19 vaccines and taking COVID-19 prevention actions are important. This is especially important if you are older or have severe health conditions or more than one health condition, including those on this list. Learn more about how CDC develops COVID-19 vaccination recommendations. If you have a medical condition, learn more about Actions You Can Take.
- The conditions on this list are in alphabetical order. They are not in order of risk.
- CDC completed a review for each medical condition on this list. This was done to ensure that these conditions met criteria for inclusion on this list. CDC conducts ongoing reviews of additional underlying conditions. If other medical conditions have enough evidence, they might be added to the list.
- Because we are learning more about COVID-19 every day, this list does not include all medical conditions that place a person at higher risk of severe illness from COVID-19. Rare medical conditions, including many conditions that mostly affect children, may not be included on the list below. We will update the list as we learn more.
- A person with a condition that is not listed may still be at greater risk of getting very sick from COVID-19 than other people who do not have the condition. It is important that you talk with your healthcare provider about your risk.
Cancer
Having cancer can make you more likely to get very sick from COVID-19. Treatments for many types of cancer can weaken your body’s ability to fight off disease. At this time, based on available studies, having a history of cancer may increase your risk.

Disabilities
People with some types of disabilities may be more likely to get very sick from COVID-19 because of underlying medical conditions, living in congregate settings, or systemic health and social inequities, including:
- People with any type of disability that makes it more difficult to do certain activities or interact with the world around them, including people who need help with self-care or daily activities
- People with attention-deficit/hyperactivity disorder (ADHD)

Immunocompromised condition or weakened immune system
Some people are immunocompromised or have a weakened immune system because of a medical condition or a treatment for a condition. This includes people who have cancer and are on chemotherapy, or who have had a solid organ transplant, like a kidney transplant or heart transplant, and are taking medication to keep their transplant. Other people have to use certain types of medicines for a long time, like corticosteroids, that weaken their immune system. One example is called primary immunodeficiency. Being immunocompromised can make you more likely to get very sick from COVID-19 or be sick for a longer period of time.
People who are immunocompromised or are taking medicines that weaken their immune system may not be protected even if they are up to date on their vaccines. Talk with your healthcare provider about what additional precautions may be necessary when respiratory viruses are causing a lot of illness in your community. Additionally, people who are moderately or severely immunocompromised may get additional doses of updated COVID-19 vaccine. Because the immune response following COVID-19 vaccination may differ in people who are moderately or severely immunocompromised, specific guidance has been developed.
People who are moderately or severely immunocompromised, are aged 12 and older, and who weigh at least 88 pounds may be eligible to get Pemivibart (Pemgarda™), a monoclonal antibody authorized to help protect against COVID-19. Pemgarda may provide another layer of protection against COVID-19 in addition to protection provided through vaccination, and can be given at least 2 weeks after receiving a COVID-19 vaccine. Pemgarda is not a treatment for COVID-19. Talk to your healthcare provider to see if Pemgarda is right for you.

People of all ages, including children, can get very sick from COVID-19. Children with underlying medical conditions are at increased risk for getting very sick compared to children without underlying medical conditions.
Current evidence suggests that children with medical complexity, with genetic, neurologic, or metabolic conditions, or with congenital heart disease can be at increased risk for getting very sick from COVID-19. Like adults, children with obesity, diabetes, asthma or chronic lung disease, sickle cell disease, or who are immunocompromised can also be at increased risk for getting very sick from COVID-19. Check out COVID-19 Vaccines for Children and Teens for more information on vaccination information for children.
Continue medications and preventive care
- Continue your medicines and do not change your treatment plan without talking to your healthcare provider.
- Have at least a 30-day supply of prescription and non-prescription medicines. Talk to a healthcare provider, insurer, or pharmacist about getting an extra supply (i.e., more than 30 days) of prescription medicines, if possible, to reduce your trips to the pharmacy.
- Follow your current treatment plan (e.g., Asthma Action Plan, dialysis schedule, blood sugar testing, nutrition, and exercise recommendations) to keep your medical condition(s) under control.
- When possible, keep your appointments (e.g., vaccinations and blood pressure checks) with your healthcare provider. Check with your healthcare provider about safety precautions for office visits and ask about telemedicine or virtual healthcare appointment options.
