People with Certain Medical Conditions and COVID-19 Risk Factors

Overview

This information is for a general audience. Healthcare professionals should see Underlying Medical Conditions Associated with Higher Risk for Severe COVID-19 for more detailed information.

If you have one or more of the conditions listed below, you are more likely to get very sick from COVID-19 and be hospitalized, need intensive care, require a ventilator to breathe, and/or die.

Risk factors for getting very sick with COVID-19

• 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 among people ages 18-29 years.
• Your risk of severe illness from COVID-19 increases as the number of your underlying medical conditions 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.

Specific information on children and teens

People of all ages, including children and teens, can get very sick from COVID-19, especially those with underlying medical conditions. This includes children and teens with:

• Medical complexity
• Genetic, neurologic, or metabolic conditions
• Congenital heart disease

Like adults, children and teens 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 Stay Up to Date on COVID-19 Vaccines for more information on vaccinating your child.

Learn how CDC develops COVID-19 vaccination recommendations.

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

Immunocompromised condition or weakened immune system

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. Examples include:

• People who have cancer and are on chemotherapy
• People who have had a solid organ transplant and are taking medication to keep their transplant
• People who use some medicines for a long time, like corticosteroids
• Primary immunodeficiency

Talk with your healthcare provider about what additional precautions may be necessary. Additionally, people who are moderately or severely immunocompromised may benefit from additional doses of updated COVID-19 vaccine. Because their immune response following COVID-19 vaccination may differ, specific guidance has been developed.
