Repopulation of facilities is allowed after thorough cleaning.

• A. True
• B. False
• C. Only after vaccination
• D. Never

Answer: (A)

The main idea here is that once a space has undergone proper cleaning and disinfection and is validated as safe, it can be re-occupied. Thorough cleaning reduces dirt and most readily removable contaminants, and disinfecting targets remaining pathogens. After those steps, and any required clearance checks or environmental validation, repopulation is appropriate. Vaccination status is not what determines whether people can return to the space—the safety of the environment itself does. So repopulation after thorough cleaning is allowed.
