If you have a preexisting medical condition—such as cancer or a heart or lung problem—you may have a higher risk of becoming seriously ill from COVID-19. Severe infection can lead to hospitalization, intensive care or even death.

Ask your doctor or health care provider about how best to manage your condition(s) and protect yourself from the virus. Staying up to date on the vaccines and taking preventive measures are important, especially if you are older, have a serious health condition or have multiple conditions.

The Centers for Disease Control and Prevention (CDC) has more information on health conditions that put you at higher risk of serious COVID-19 and actions you can take.
