Including but not limited to laboratories, classrooms, common sitting areas, meal rooms, etc.

Including but not limited to laboratories, classrooms, common sitting areas, meal rooms, etc.

Unless a person with known or suspected COVID-19 has been in an area, current CDC guidance does NOT recommend additional cleaning, disinfection or precautions for common community areas such as classrooms, laboratories, common sitting areas, meal rooms, etc. Routine cleaning of these areas is all that is necessary. However, facilities should establish a program of regular cleaning of common touchpoints, such as door handles, at least once per day. All personnel are encouraged to wash hands with soap and water or to use hand sanitizer after handling high-touch common-use areas. The guidance that follows below is for community areas to be cleaned and disinfected when documented and confirmed that a person with known or suspected COVID-19 has been present for 15 minutes or longer within the past 24 hours. If more than 24 hours have passed since a person with known or suspected COVID-19 has been present for 15 minutes or longer, cleaning as described in section A below is sufficient. If more than 72 hours have passed since a person with known or suspected COVID-19 has been present for 15 minutes or longer, cleaning as described in section B below is sufficient.

Note: Use of the Clorox 360 sprayer is no longer recommended.

Cleaning and Disinfection after Persons Suspected/Confirmed to Have COVID-19 Have Been in the Facility within the Past 24 Hours:

  • Timing and surfaces
    • Open outside doors and windows and use ventilating fans to increase air circulation in the area. The room, at a minimum, needs to have undergone at least 6 air exchanges before re-entry. Depending on the characteristics of the ventilation system, this may be 8 hours or less.
    • Facilities staff should clean and disinfect all areas, such as offices, bathrooms, common areas and shared electronic equipment (like tablets, touch screens, keyboards, remote controls and ATM machines) used by the ill persons, focusing on frequently touched surfaces.
  • To clean and disinfect:
    • Put on gloves and remove trash from the area. (PPE: Gloves, surgical mask)
    • If the area requires vacuuming, use a vacuum with a HEPA filter. (PPE: Gloves, N95 Mask, Goggles)
    • Examine the room for visibly dirty or dusty areas and clean them with a cloth and cleaner so that the disinfectant can make direct contact with the surface. (PPE: Gloves, N95 Mask, Goggles)
    • Follow instructions on disinfectant to ensure correct application and contact time.
    • Work in one area of the room to apply disinfectant to all accessible surfaces. Surfaces should be visibly wet with product
    • Wait until the contact time is over and then wipe with a clean cloth. Complete other areas in the same manner.

Cleaning after Persons Suspected/Confirmed to Have COVID-19 Have Been in the Facility between 24 and 72 hours ago

  • Timing and surfaces:
    Facilities staff should focus on cleaning all high touch areas, such as bathrooms, door handles, light switches and shared electronic equipment (like tablets, touch screens, keyboards, remote controls and ATM machines) used by the ill persons.
