Updated Oct. 16, 2020

Revisions were made on October 6, 2020 to reflect recent data supporting increased risk of severe illness from the virus that causes COVID-19 among adults with COVID-19 who have obesity, who have overweight, or who smoke or have a history of smoking. These revisions also make the document more explicit about data and implications for adults and for children. The listed underlying medical conditions in children were also revised to indicate that these conditions might increase risk to better reflect the quality of available data currently. This reflects the fact that there are less data available for children and does not imply that children are not at risk. We are learning more about COVID-19 every day, and as new information becomes available, CDC will update the information below. ​

Adults of any age with certain underlying medical conditions are at increased risk for severe illness from the virus that causes COVID-19:

Adults of any age with the following conditions are at increased risk of severe illness from the virus that causes COVID-19:

• Cancer

• Chronic kidney disease

• COPD (chronic obstructive pulmonary disease)

• Heart conditions, such as heart failure, coronary artery disease, or cardiomyopathies

• Immunocompromised state (weakened immune system) from solid organ transplant

• Obesity (body mass index [BMI] of 30 kg/m2 or higher but < 40 kg/m2)

• Severe Obesity (BMI ≥ 40 kg/m2)

• Sickle cell disease

• Smoking

• Type 2 diabetes mellitus

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, adults of any age with the following conditions might be at an increased risk for severe illness from the virus that causes 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

• Overweight (BMI > 25 kg/m2, but < 30 kg/m2)

• Pregnancy

• Pulmonary fibrosis (having damaged or scarred lung tissues)

• Thalassemia (a type of blood disorder)

• Type 1 diabetes mellitus
