Cleaning and Disinfection Protocol After a Positive COVID-19 Diagnosis

To protect public health and safety, the University of Houston adheres to Centers for Disease Control and Prevention (CDC) guidelines for cleaning and disinfecting when a person diagnosed or tested positive for COVID-19 has been on campus.

The cleaning after a positive diagnosis protocol is in addition to the normal and enhanced cleaning practices employed by the University.


  1. Case is Reported
    Individual self-reports his or her positive COVID-19 status to the University through the online Reporting COVID-19 Diagnosis form.

    Note: Users are encouraged to input complete and accurate building names and room numbers so that the areas can be found and cleaned promptly. Failure to do so may delay the process. Please only list buildings and rooms that you have been in for 15 minutes or more.

  2. UH Facilities Services is Notified
    If the individual has been on campus within the last 3 days, University of Houston Facilities Services (FS) is automatically notified to begin the cleaning after a positive COVID-19 diagnosis protocol.

    Note: FS receives positive COVID-19 case notifications 24-7. Notifications received after business hours and on weekends are acted upon as quickly as possible. However, they may experience a delay in the execution of the protocols if additional details or location information is needed.

    In accordance with CDC guidelines, if the individual’s date of last activity in a facility was greater than 3 days, no additional cleaning or disinfection is required. Learn more about the CDC Cleaning and Disinfecting Your Facilities guidelines.

  3. Affected Areas are Identified and Closed
    FS contacts the designated building coordinator(s) to schedule cleaning of the spaces and dispatches technicians to place appropriate signage and secure the area. In some cases, departments notified of a potential positive COVID-19 case may have already secured the area.

    • FS may request assistance from the building coordinator to identify the room or spaces that need cleaning and disinfection when the location information is unclear.
    • The building coordinators will notify the point of contact responsible for the spaces that will be closed for cleaning. 
  4. Professional Cleaning Crew is Deployed
    FS schedules the COVID-19 cleaning contractor, and the area is cleaned and disinfected per CDC cleaning guidelines. 

    The cleaning contractor is a professional cleaning agency that specializes in disaster response cleanups and CDC protocols for COVID-19 cleaning and disinfection.

  5. Affected Areas are Reopened
    After cleaning, the area is given a two-hour settling period to ensure the efficacy of the cleaning and disinfection solutions. Following the two-hour settling period, FS removes the signage and the area is reopened for use. The designated building coordinator is notified.
