Center for Digital Health


covidWe have re-released the MyCOVIDRisk App

In 2020, the Brown-Lifespan Center for Digital Health developed a free and publicly available COVID-19 risk estimation and mitigation tool in response to the COVID-19 pandemic. It has been accessed nearly 1.3 million times (and counting!) since launch, demonstrating the acceptability of a free and simple web-based mobile application to estimate risk of COVID-19 transmission.

In our latest update of the app, we refined our risk assessment to include factors such as Delta prevalence, individual vaccination status, and vaccination status of household members for indoor activities. We have also implemented a help guide to assist users and make the app more accessible.

How It Works

Users input the following information about the activity they want to know an estimated risk score for:

  • Self-Check Screener
  • Activity Location
  • Indoor / Outdoor
  • Activity Planned
  • Activity Level
  • Breathing Rate
  • Room Size
  • Ventilation
  • Duration of Stay
  • Number of People
  • Percentage Wearing Masks

Initial Risk Score

Users receive an initial risk score estimate, which can then be lowered by choosing mitigation measures such as:

  • Local COVID-19 Prevalence Data by County
  • Indoor / Outdoor Risk
  • Activity Level: Resting, Standing, Light Exercise, Heavy Exercise
  • Breathing Rate: Breathing, Speaking, Loudly Speaking
  • Room Volume
  • Ventilation 
  • Duration of Stay
  • Number of People at Activity
  • Percentage of Mask Wearers

Mitigation Measures

Users are prompted to reduce their estimated risk score by inputting the following mitigation measures:

  • My Vaccine Status
  • Wear a Mask + Select Fabric / Layers
  • Social Distance
  • Indoor Activity Only: % fully vaccinated people at your activity
  • Reduce Activity Time
  • Wash Hands Frequently
  • Wear Eye Protection
  • Increase Ventilation

Final Risk Score
