What's the best guidance for cleaning a facility when someone may have been sick?

Last Updated: 04/20/2020

It is recommended to close off areas used by anyone who is ill or has symptoms and wait as long as practical before beginning cleaning and disinfection to minimize potential for exposure to respiratory droplets. Open outside doors and windows to increase air circulation in the area. If possible, wait up to 24 hours before beginning cleaning and disinfection.

To clean and disinfect areas where ill persons have visited or used, follow the CDC's guidelines on cleaning and disinfection.
