Shielding is an extreme form of social distancing that should be practiced by people who are at greater risk of developing severe illness with COVID-19. Some people in this group may decide that the risk of not shielding is worth taking if it means they don't need to sacrifice the small pleasures of human interactions and leaving the house. In addition, they may not have the support they need from friends and family or the community to stay home. We can help them to shield.
