Your Health Back to COVID-19 Home PEOPLE WITH CERTAIN MEDICAL CONDITIONS Medical Conditions Updated Feb. 10, 2023 Español | Other Languages Print minus Related Pages As of January 26, 2023, EVUSHELDTM is not currently authorized for emergency use because it is unlikely to be active against the majority of SARS-CoV-2 variants circulating in the United States. If you or your family member are at high risk for severe illness, wear a mask or respirator with greater protection in public indoor spaces if you are in an area with a high COVID-19 Community Level. Talk with your healthcare provider about wearing a mask in a medium COVID-19 Community Level. 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 few days of 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. 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. * 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 (primary series and booster) are safe and effective. * Some people who are immunocompromised, or people with weakened immune systems, may be eligible for an additional primary dose of COVID-19 vaccine. On this Page * Overview * Medical Conditions * Additional Information on Children and Teens * Actions You Can Take 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. Top of Page MEDICAL CONDITIONS * 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.

Get more information: * HIV Infection * Interim Guidance for COVID-19 and Persons with HIV 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. Such long-term uses can lead to secondary or acquired immunodeficiency. Other people have a weakened immune system because of a life-long condition. For example, some people inherit problems with 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 wearing a mask in a medium COVID-19 Community Level and what additional precautions may be necessary in medium or high COVID-19 Community Levels. After completing the primary vaccination series, some people who are moderately or severely immunocompromised should get an additional primary dose and a booster. Because the immune response following COVID-19 vaccination may differ in people who are moderately or severely immunocompromised, specific guidance has been developed.

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. * COVID-19 Vaccines for Children and Teens Top of Page ACTIONS YOU CAN TAKE It is important to protect yourself and others by taking COVID-19 prevention actions: * Stay up to date with your COVID-19 vaccines * Improve ventilation * Get tested if you have symptoms * Follow recommendations for what to do if you have been exposed * Stay home if you have suspected or confirmed COVID-19 * Seek treatment if you have COVID-19 and are at high risk of getting very sick * Avoid contact with people who have suspected or confirmed COVID-19 * Wear a mask or respirator * Increase space and distance Please contact your state, tribal, local, or territorial health department for more information on COVID-19 vaccination in your area. It is also important for people with medical conditions and their healthcare providers to work together and manage those conditions carefully and safely. Stay up to date with your COVID-19 vaccines. If you have a medical condition, the following are actions you can take based on your medical conditions and other risk factors. BUILD YOUR PERSONAL COVID-19 PLAN Put together your COVID-19 plan so you have all the information you need on hand if you get sick with COVID-19. Download, edit and save, and share your plan with your family, friends, and healthcare provider. File Details: 561 KB, 3 pages View PDF in EnglishOther Languages SEEK CARE WHEN NEEDED * Call your healthcare provider if you have any concerns about your medical conditions or if you get sick and think that you may have COVID-19. Discuss steps you can take to manage your health and risks. If you need emergency help, call 911 right away. * Do not delay getting care for your medical condition because of COVID-19. Emergency departments, urgent care, clinics, and your healthcare provider have infection prevention plans to help protect you from getting COVID-19 if you need care. 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. * Learn about stress and coping. You may feel increased stress during this pandemic. Fear and anxiety can be overwhelming and cause strong emotions. It can be helpful to talk with a professional like a counselor, therapist, psychologist, or psychiatrist. Ask your primary care provider if you would like to speak with a professional. Getting regular exercise and being physically active is also a great way to reduce stress. ACCOMMODATE DIETARY NEEDS AND AVOID TRIGGERS * Have non-perishable food choices such as canned goods available that meet your needs based on your medical condition (e.g., kidney diet and KCER 3-Day Emergency Diet Plan, diabetic diet). * Know the triggers for your condition and avoid when possible (e.g., avoid asthma triggers by having another member of your household clean and disinfect your house for you or avoid possible sickle cell disease triggers to prevent pain crises).
