TABLE. Uses of WBS Data in Conjunction With Clinical Surveillance Data for Public Health During the COVID-19 Pandemic.

Institutional Public Health Actions Communications Stakeholder Relationships
  • Inform frequency, location, and timing of clinical surveillance testing

  • Inform proportion of population to test clinically

  • Confirm case-positive staff members are not at the facility or confirm case-positive student moved out of dormitory

  • Allocate additional funding for contact tracing and clinical surveillance

  • Adjust length of quarantines, (eg, shorten quarantine durations if no wastewater signal for several days)

  • Support social distancing (eg, establish strict schedules for use of common spaces)

  • Give higher-risk staff members tasks with less resident contact to reduce risk of transmission

  • Plan and obtain needed supplies (ie, order personal protective equipment)

  • Mandate more protective equipment for staff (ie, N95 masks instead of surgical masks)

  • Resume social programming after a COVID-19 exposure

  • Advise health staff with patient contact to be on the lookout for potential symptoms

  • Inform residents' personal protective behaviors (ie, handwashing, masking, social distancing)

  • Provide reassurance that clinical surveillance strategy is adequate for timely identification of cases

  • Justify or explain public health actions (eg, social distancing, masking)

  • Encourage voluntary clinical testing

  • Provide reassurance to decision makers and clinical practitioners that there is not a hidden outbreak emerging

  • Initiate discussions with health department to determine when to come out of “outbreak” status

  • Raise surrounding community's confidence in the institution's pandemic response efforts

  • Document due diligence in public health care of residents in case of a lawsuit

  • Demonstrate institution's technical expertise and data-driven public health responsiveness

  • Show that the resident population did not pose a public health risk to the surrounding community
