Cleaning and disinfecting your building or facility when someone is sick or has a COVID-19 diagnosis
Close off areas used by the person who is sick.
Open outside doors and windows and use fans or other engineering controls to increase air circulation in the area. Wait 24 hours before you clean or disinfect. If 24 hours is not feasible, wait as long as possible.
Clean and disinfect the immediate workspace used by the person who is sick or diagnosed with COVID-19, such as the surfaces in their office or cubicle. If common areas such as bathrooms or shared items have already been routinely cleaned and disinfected, there is no need for additional action.
