Currently, it is unknown if recovered adults are definitively immune to SARS-CoV-2 reinfection because biologic markers of immunity have not been correlated with protection from infection. If the present guidance is implemented with current prevention strategies to prevent SARS-CoV-2 transmission (i.e., wear masks, stay at least 6 feet away from others who do not live with you, avoid crowds, and wash hands regularly), the risks of potential SARS-CoV-2 transmission from recovered adults is generally too low to justify retesting and quarantine.

Place together (cohort) patients who are presumed to have the same infection( based on clinical presentation and diagnosis when known) in areas of the facility that are away from other patients, especially patients who are at increased risk for infection (e.g., immunocompromised patients).
