Webinar hosted by CPWR-The Center for Construction Research & Training, July 16, 2020
![Page 13: COVID-19 Webinar Series: Contact Tracing—How it’s done ...€¦ · Workplace Infection Control and Response (WICAR) Tool. Roles and Responsibilities - Workplace Contact Tracing](https://reader033.fdocuments.net/reader033/viewer/2022051914/600539cd49044767796dc49d/html5/thumbnails/13.jpg)
Background
Core disease control measures employed by local and state health department personnel for decades (e.g., TB, STD)
– Case investigation: working with a patient who has been diagnosed with an infectious disease
• Public health staff work with a patient to help them recall everyone with whom they have had close contact during the timeframe while they may have been infectious
– Contact tracing: providing support to people (contacts) who may have been infected through close contact with the patient
![Page 14: COVID-19 Webinar Series: Contact Tracing—How it’s done ...€¦ · Workplace Infection Control and Response (WICAR) Tool. Roles and Responsibilities - Workplace Contact Tracing](https://reader033.fdocuments.net/reader033/viewer/2022051914/600539cd49044767796dc49d/html5/thumbnails/14.jpg)
Overview
Case investigation and contact tracing are essential interventions in a successful, multipronged response to COVID-19
All confirmed (symptomatic and asymptomatic) and probable COVID-19 patients should receive follow-up to prevent further spread of the virus in the community
Prompt identification and isolation of patients and quarantine of contacts can effectively break the chain of disease transmission
![Page 15: COVID-19 Webinar Series: Contact Tracing—How it’s done ...€¦ · Workplace Infection Control and Response (WICAR) Tool. Roles and Responsibilities - Workplace Contact Tracing](https://reader033.fdocuments.net/reader033/viewer/2022051914/600539cd49044767796dc49d/html5/thumbnails/15.jpg)
Authority & Resources
Authority and responsibility for these interventions are vested in state, tribal, local, and territorial health departments
Multisector partnerships are essential to scale up comprehensive case investigation and contact tracing for COVID-19
CDC’s Health Department Contact Tracing Resources
![Page 16: COVID-19 Webinar Series: Contact Tracing—How it’s done ...€¦ · Workplace Infection Control and Response (WICAR) Tool. Roles and Responsibilities - Workplace Contact Tracing](https://reader033.fdocuments.net/reader033/viewer/2022051914/600539cd49044767796dc49d/html5/thumbnails/16.jpg)
Prioritization
Case and contact follow-up must happen quickly to be successful Particular consideration should be given to
– Potential for disease complications among patients with underlying health conditions
– Potential to expose others at higher risk for severe disease– Potential for spread (exposure of numerous people)– Potential to interrupt critical infrastructure
![Page 17: COVID-19 Webinar Series: Contact Tracing—How it’s done ...€¦ · Workplace Infection Control and Response (WICAR) Tool. Roles and Responsibilities - Workplace Contact Tracing](https://reader033.fdocuments.net/reader033/viewer/2022051914/600539cd49044767796dc49d/html5/thumbnails/17.jpg)
Technology Assets Digital Tools can enhance program functionality in a number of areas
– Surveillance systems and case management– Contact tracing data management– Active monitoring—daily temperature and symptom checks—of
patients (during isolation) & contacts (during quarantine)– Inter-jurisdictional collaboration
• Essential with cross jurisdictional outbreaks, flight exposures, travel of critical infrastructure workers, etc.
– Exposure notification using proximity apps Digital Contact Tracing Tools for COVID-19—this fact sheet describes
different digital contact tracing tools for COVID-19 by primary purpose and primary user
![Page 18: COVID-19 Webinar Series: Contact Tracing—How it’s done ...€¦ · Workplace Infection Control and Response (WICAR) Tool. Roles and Responsibilities - Workplace Contact Tracing](https://reader033.fdocuments.net/reader033/viewer/2022051914/600539cd49044767796dc49d/html5/thumbnails/18.jpg)
Referral to Isolation Health Care Providers
– Refer to home isolation ASAP with symptom-based diagnosis or positive viral test
Businesses and Workplaces– Refer to home isolation ASAP when identified as
symptomatic during a workplace health screening (e.g., temperature check & symptom screen upon entry/exit) or after a positive viral test through a workplace testing program
![Page 19: COVID-19 Webinar Series: Contact Tracing—How it’s done ...€¦ · Workplace Infection Control and Response (WICAR) Tool. Roles and Responsibilities - Workplace Contact Tracing](https://reader033.fdocuments.net/reader033/viewer/2022051914/600539cd49044767796dc49d/html5/thumbnails/19.jpg)
Case Investigation & Contact Tracing in the Workplace Health departments can typically perform with existing staff
– Surge staff rarely needed COVID-19 response may be delayed due to
– Large volume of patients – Quick and easy transmission
Employers can prepare and help limit the spread in the workplace
![Page 20: COVID-19 Webinar Series: Contact Tracing—How it’s done ...€¦ · Workplace Infection Control and Response (WICAR) Tool. Roles and Responsibilities - Workplace Contact Tracing](https://reader033.fdocuments.net/reader033/viewer/2022051914/600539cd49044767796dc49d/html5/thumbnails/20.jpg)
Health Department Collaboration with Employer
When a case is identified that impacts a work environment, the health department may:
– Not engage with the employer
– Ask for employer’s help in understanding the work environment and identifying exposures and contacts in the work setting
– Rely on the employer to carry out the case investigation and contact tracing of employees in the work environment
![Page 21: COVID-19 Webinar Series: Contact Tracing—How it’s done ...€¦ · Workplace Infection Control and Response (WICAR) Tool. Roles and Responsibilities - Workplace Contact Tracing](https://reader033.fdocuments.net/reader033/viewer/2022051914/600539cd49044767796dc49d/html5/thumbnails/21.jpg)
Preparing for Case Investigation and Contact Tracing
Before a case, employers can – Identify a COVID Coordinator or a COVID Team to oversee COVID-19
activities– Identify, and if possible, contact or visit the health department website– Create a COVID-19 preparedness, response, and control plan– Review CDC’s case investigation and contact tracing guidance to
prepare to interact with public health– Encourage employees to work with the health department
![Page 22: COVID-19 Webinar Series: Contact Tracing—How it’s done ...€¦ · Workplace Infection Control and Response (WICAR) Tool. Roles and Responsibilities - Workplace Contact Tracing](https://reader033.fdocuments.net/reader033/viewer/2022051914/600539cd49044767796dc49d/html5/thumbnails/22.jpg)
Preparing for Case Investigation and Contact Tracing
After a case, employers can– Prepare and quickly provide information and records about
• The workplace• Potential workplace contacts • Workplace operations without revealing confidential personnel
records or confidential business information– Respond by supporting employees, and then follow up quickly by doing
workplace hazard evaluation and prevention activities
![Page 23: COVID-19 Webinar Series: Contact Tracing—How it’s done ...€¦ · Workplace Infection Control and Response (WICAR) Tool. Roles and Responsibilities - Workplace Contact Tracing](https://reader033.fdocuments.net/reader033/viewer/2022051914/600539cd49044767796dc49d/html5/thumbnails/23.jpg)

Roles and Responsibilities - Workplace Contact Tracing Collaboration is essential to interrupting the spread of COVID-19 in
the workplace– Roles and responsibilities should be discussed between health
departments and employers– All activities conducted must be in accordance with applicable
public health authorities, and workplace and medical privacy and confidentiality laws

![Page 28: COVID-19 Webinar Series: Contact Tracing—How it’s done ...€¦ · Workplace Infection Control and Response (WICAR) Tool. Roles and Responsibilities - Workplace Contact Tracing](https://reader033.fdocuments.net/reader033/viewer/2022051914/600539cd49044767796dc49d/html5/thumbnails/28.jpg)
Contact Tracing In Construction
• Process used to identify, educate, and monitor people who have had close contact with an infected person
• Increased risk for infection and spreading the virus to others
• Helps exposed individuals understand their risk and limit further spread
![Page 29: COVID-19 Webinar Series: Contact Tracing—How it’s done ...€¦ · Workplace Infection Control and Response (WICAR) Tool. Roles and Responsibilities - Workplace Contact Tracing](https://reader033.fdocuments.net/reader033/viewer/2022051914/600539cd49044767796dc49d/html5/thumbnails/29.jpg)
![Page 30: COVID-19 Webinar Series: Contact Tracing—How it’s done ...€¦ · Workplace Infection Control and Response (WICAR) Tool. Roles and Responsibilities - Workplace Contact Tracing](https://reader033.fdocuments.net/reader033/viewer/2022051914/600539cd49044767796dc49d/html5/thumbnails/30.jpg)
Goals of Contact Tracing
• Interrupt ongoing transmission
• Reduce the spread • Alert contacts to the
possibility of infection • Offer preventive counseling
or prophylactic care• Offer diagnosis, counseling,
and treatment to already infected individuals
• Learn about the epidemiology of a disease in a particular population
![Page 31: COVID-19 Webinar Series: Contact Tracing—How it’s done ...€¦ · Workplace Infection Control and Response (WICAR) Tool. Roles and Responsibilities - Workplace Contact Tracing](https://reader033.fdocuments.net/reader033/viewer/2022051914/600539cd49044767796dc49d/html5/thumbnails/31.jpg)
Time is of the essence
• Identifying contacts and ensuring they do not interact with others is critical to protect from further spread.
• Case investigators and contact tracers need to:– Immediately identify and interview people with SARS CoV-2
infections and COVID-19 (i.e., disease)– Support isolation of those who are infected– Warn contacts of their exposure, assess their symptoms and risk, and
provide instructions for next steps– Link those with symptoms to testing and care
![Page 32: COVID-19 Webinar Series: Contact Tracing—How it’s done ...€¦ · Workplace Infection Control and Response (WICAR) Tool. Roles and Responsibilities - Workplace Contact Tracing](https://reader033.fdocuments.net/reader033/viewer/2022051914/600539cd49044767796dc49d/html5/thumbnails/32.jpg)
Benefits
• Educates infected people about what steps to take to avoid further spread
• Helps exposed contacts separate themselves from others to stop the spread
• Links infected and exposed people with community resources during quarantine or self-isolation
![Page 33: COVID-19 Webinar Series: Contact Tracing—How it’s done ...€¦ · Workplace Infection Control and Response (WICAR) Tool. Roles and Responsibilities - Workplace Contact Tracing](https://reader033.fdocuments.net/reader033/viewer/2022051914/600539cd49044767796dc49d/html5/thumbnails/33.jpg)
Limitations
• Doesn’t stop all asymptomatic spread
• Must be done quickly to be effective – Cannot hesitate
• Potential privacy and confidentiality issues
• Relies on buy-in and cooperation
![Page 34: COVID-19 Webinar Series: Contact Tracing—How it’s done ...€¦ · Workplace Infection Control and Response (WICAR) Tool. Roles and Responsibilities - Workplace Contact Tracing](https://reader033.fdocuments.net/reader033/viewer/2022051914/600539cd49044767796dc49d/html5/thumbnails/34.jpg)
How Employers Can Assist
• Maintain attendance records, including employees’ scheduled shifts
• Keep track of EVERYONE who enters the jobsite
• Take the extra steps of keeping track of workers within specific areas, groups of workers who work together on a specific task or workers who are in close contact
![Page 35: COVID-19 Webinar Series: Contact Tracing—How it’s done ...€¦ · Workplace Infection Control and Response (WICAR) Tool. Roles and Responsibilities - Workplace Contact Tracing](https://reader033.fdocuments.net/reader033/viewer/2022051914/600539cd49044767796dc49d/html5/thumbnails/35.jpg)
What About Workers?
• The intention isn’t to interrogate or pass judgment – it’s to collect information to keep everyone safe
• All data collected during this process must be kept confidential
• Only used to track COVID-19 cases and monitor risk in the workplace
![Page 36: COVID-19 Webinar Series: Contact Tracing—How it’s done ...€¦ · Workplace Infection Control and Response (WICAR) Tool. Roles and Responsibilities - Workplace Contact Tracing](https://reader033.fdocuments.net/reader033/viewer/2022051914/600539cd49044767796dc49d/html5/thumbnails/36.jpg)
