CDC: Underlying Conditions Increase Risk of COVID-19
People of Any Age with Underlying Medical Conditions
Updated June 25, 2020
Summary of Recent Changes
Revisions were made on June 25, 2020 to reflect available data as of May 29, 2020. We are learning more about COVID-19 every day, and as new information becomes available, CDC will update the information below.
People of any age with certain underlying medical conditions are at increased risk for severe illness from COVID-19:
People of any age with the following conditions are at increased risk of severe illness from COVID-19:
- Chronic kidney disease
- COPD (chronic obstructive pulmonary disease)
- Immunocompromised state (weakened immune system) from solid organ transplant
- Obesity (body mass index [BMI] of 30 or higher)
- Serious heart conditions, such as heart failure, coronary artery disease, or cardiomyopathies
- Sickle cell disease
- Type 2 diabetes mellitus
Children who are medically complex, who have neurologic, genetic, metabolic conditions, or who have congenital heart disease are at higher risk for severe illness from COVID-19 than other children.
COVID-19 is a new disease. Currently there are limited data and information about the impact of underlying medical conditions and whether they increase the risk for severe illness from COVID-19. Based on what we know at this time, people with the following conditions might be at an increased risk for severe illness from COVID-19:
- Asthma (moderate-to-severe)
- Cerebrovascular disease (affects blood vessels and blood supply to the brain)
- Cystic fibrosis
- Hypertension or high blood pressure
- Immunocompromised state (weakened immune system) from blood or bone marrow transplant, immune deficiencies, HIV, use of corticosteroids, or use of other immune weakening medicines
- Neurologic conditions, such as dementia
- Liver disease
- Pulmonary fibrosis (having damaged or scarred lung tissues)
- Thalassemia (a type of blood disorder)
- Type 1 diabetes mellitus
The list of underlying conditions is meant to inform clinicians to help them provide the best care possible for patients, and to inform individuals as to what their level of risk may be so they can make individual decisions about illness prevention. We are learning more about COVID-19 every day. This list is a living document that may be updated at any time, subject to potentially rapid change as the science evolves.
Reduce your risk of getting COVID-19
It is especially important for people at increased risk of severe illness from COVID-19, and those who live with them, to protect themselves from getting COVID-19.
The best way to protect yourself and to help reduce the spread of the virus that causes COVID-19 is to:
- Limit your interactions with other people as much as possible.
- Take precautions to prevent getting COVID-19 when you do interact with others.
If you start feeling sick and think you may have COVID-19, get in touch with your healthcare provider within 24 hours.
Venturing out into a public setting? What to consider before you go.
As communities and businesses across the United States are opening, you may be thinking about resuming some activities, running errands, and attending events and gatherings. There is no way to ensure you have zero risk of infection, so it is important to understand the risks and know how to be as safe as possible.
People at increased risk of severe illness from COVID-19, and those who live with them, should consider their level of risk before deciding to go out and ensure they are taking steps to protect themselves. Consider avoiding activities where taking protective measures may be difficult, such as activities where social distancing can’t be maintained. Everyone should take steps to prevent getting and spreading COVID-19 to protect themselves, their communities, and people who are at increased risk of severe illness.
In general, the more people you interact with, the more closely you interact with them, and the longer that interaction, the higher your risk of getting and spreading COVID-19.
- If you decide to engage in public activities, continue to protect yourself by practicing everyday preventive actions.
- Keep these items on hand and use them when venturing out: a cloth face covering, tissues, and a hand sanitizer with at least 60% alcohol, if possible.
- If possible, avoid others who are not wearing cloth face coverings or ask others around you to wear cloth face coverings.
