Because cancer treatments weaken the body's immune system, cancer patients are among those at higher risk of severe illness from COVID-19. To protect yourself from COVID-19, follow Centers for Disease Control and Prevention (CDC) recommendations for people who need to take extra precautions.

Mayo Clinic now requires all patients, visitors and staff to wear a face covering or mask while at Mayo Clinic. See the CDC's information on the use of cloth face coverings to help slow the spread of COVID-19.

In addition, please continue to follow the CDC's recommendations for people at high risk of COVID-19.

Mayo Clinic recommends travelers follow CDC recommendations.
