How Will You Meet The CDC Guidelines For Returning To Work?

When looking for a reopening solution for your organization, you need to know how it will meet CDC guidelines for returning to work. The key criterion for such organizations are outlined in the CDC’s ‘Restart Readiness Checklist’. Let’s see how our solution can help you tick those boxes. 

CDC Guidelines For Returning To Work

Monitor federal, state, and local public health communications about COVID-19

In order to stay ahead of COVID-19, you need access to up to date federal, state, and local COVID-19 information and guidelines. Our experts are constantly monitoring the situation and we will ensure that you are in compliance with all necessary guidelines. 

Ensure workers have access to current information 

Keeping your employees informed gives them peace of mind knowing that you are looking out for their best interests. When an administrator receives a COVID-19 update they can notify their employees and/or adjust their workplace policies if needed via our screening and contact tracing app. 

Check local public health information and the CDC COVID-19 website daily, or as needed depending on local conditions.

An effective solution is localized and customizable. Our platform’s policy recommendations are informed by local public health guidance. 

Reinforce how employees can protect themselves and others from COVID-19 by communicating: 

If you have symptoms, notify your supervisor and stay home.

If you are sick, follow CDC recommended steps, and do not return to work until you meet criteria to discontinue home isolation. 

An effective solution educates and empowers employees to monitor and protect themselves. Our daily screening app generates customized employee recommendations daily. Users receive reminders to record symptoms in a quick and easy-to-use daily screening survey. After completing the screening process the app generates a recommendation to come to work or stay home based on the policies your organization has in place. Employers can fine-tune sick employees’ recommendations to meet their organization’s preferences and align with CDC guidelines for returning to work in their area. 

Plan for conducting daily in-person or virtual health checks (e.g. symptom and/or health screenings) before employees enter the facility. 

The CDC guidelines for returning to work recommend that organizations implement a daily screening protocol for employees to follow before they enter the workplace. In-person screenings invite workplace exposure to symptomatic employees. Our digital screening solution eliminates this risk by giving people the ability to screen before they leave their house via our mobile app. 

Establish social distancing policies and practices 

Utilizing Bluetooth technology, our app has a social distance alarm feature that can buzz to let employees know if they have come within 6 feet of another person for more than 1-minute. This helps users monitor their behavior and ensure they are practicing social distancing throughout the workday. 

Develop an action plan for suspected/confirmed cases

In order to effectively combat the pandemic you must have a plan in place to respond to sick employees and/or confirmed COVID-19 cases. This plan must ensure infected employees isolate and potentially exposed employees are contacted. Our BioSecurity Portal allows you to immediately alert exposed employees while maintaining the infected employee’s confidentiality. If someone tests positive for COVID-19 our solution automatically triggers contact tracing based on the bluetooth data collected and the symptom screening information to discover who is potentially at risk for transmission.

GPS vs Bluetooth Technology for Contact Tracing

GPS vs Bluetooth Technology for Contact Tracing

ThiOur objective with this post is to compile an objective analysis of the relative strengths and weaknesses of Bluetooth vs GPS for the purposes of contact tracing and how best to leverage them both for the purposes of contact tracing and social distance alarms.  


  • Location | GPS: Global Positioning System (GPS) refers to the blended location information provided by Apple and Google mobile OS SDKs that combines GPS, Wifi & Cell Tower, Accelerometer data using Kalman filters, ML to increase accuracy beyond just GPS
  • Direct Proximity Detection | Bluetooth: refers to the use of Bluetooth to detect proximity with other Bluetooth devices running in the background.  

Basic Comparison

The question is do we use location history to infer when two people were in close proximity or do we use Bluetooth to actively detect proximity.

GPS vs. Bluetooth for contact tracing

GPS Negatives

Accuracy drops to unusable in subways. Can’t handle indoors and underground scenarios particularly well.

GPS collects exact location information and uses it to perform contact matching.  However, location data is highly sensitive and difficult to secure.  For instance, the use of GPS location data in fitness apps revealed the exact layout of US bases, and location data is so unique that 1000% anonymization is effectively impossible.  Deployment of location-based contact tracing at scale thus poses privacy and security risks if it can’t be completely secured.

GPS Battery Usage

The rate of battery usage is dependent on: accuracy, frequency, and latency. These parameters can be adjusted, but they trade off against one another.

The highest accuracy setting uses GPS and all other signals and inputs available, which significantly drains battery. The balanced accuracy setting uses less power, primarily relies on WIFI and cell signals, and only occasionally uses GPS.

Bluetooth Accuracy

Bluetooth based proximity detection “uses received signal strength indicator (RSSI) values to measure the signal strength between phones. Calibrated RSSI values are used to estimate the approximate distance between users during an encounter.” (Source)

Range: Up to 10 Meters

Bluetooth Negatives

iOS sometimes terminates the Bluetooth scanning when the app is running in the background. Does bluetooth need to be enabled during the entire time frame for it to work? (No, just bluetooth app permission enabled)

Foreground vs Background app

Medical Considerations

What % of cases are transmitted through the air vs. surfaces?

COVID-19 can survive on surfaces for potentially days, but if the % of cases that are spread through surfaces is insignificant, then the advantage of GPS+cell to track historical location becomes less relevant. I believe more research needs to be done on what proportion of cases are spread through surfaces.

What is a “safe distance” with respect to airborne transmission?

Maximum plausible distance to get infected so far: within 18ft of an infected person (in a closed air environment)

Passengers in a Wuhan bus got infected from 4.5m (15ft) away, within 30min:

COVID-19 spread through a bus

Aerosols dispersed at least 6ft away are still infectious (Bischoff).

Particles from a sneeze or cough can travel up to 2.5m (8ft) horizontally and up to 6m (20ft) vertically (which can reach air ducts & ventilation systems) (MIT).

This study analyzes the spread of SARS 1 on an aircraft (NEJM) (note for scale: 3 rows = 90 inches).
