Why participate
An elevated temperature can be an indicator that your body is fighting off an infection. Some people contract COVID-19 but never know they have it, because other than a minor increase in temperature, they never show any other symptoms. As we gear up to restart the ecomomy a critical requirement for all employers is to take precautions, and central to that is taking employee temperatures every day. By copying your temperature from your physical thermometer into a virtual thermometer using this site, you will not only be following the guidelines necessary to get back to work, you will be contributing your temperature to build a national real-time dataset that will help researchers track and combat the spread of COVID-19. We do this while maintaining your privacy, and you only need a web browser on your smartphone or computer and an existing thermometer to participate.
