The Centers for Disease Control and Prevention (CDC) in the U.S. recommend some guidelines for cancer patients, which they consider a high-risk population, and their caregivers to protect them from COVID-19. The basic recommendations are the same as what they suggested to the general public, which includes watching out for fever (38ºC or higher), knowing the signs and symptoms of infection, cleaning your hands often, avoiding touching one's face, using a face covering, avoiding people as much as possible, and keeping a distance of at least 6 feet (2 m).
