Description:

The Soterius Scout is a passive biosensor that will detect exposure to Covid 19 and other respiratory viruses.

The Scout can be worn as a fob, or attached as a fixture within a workspace. It detects virus particles landing on its sensor, and communicates this result to a smartphone or a reader which users swipe as they enter or exit areas.

If exposure is detected, the user can be directed immediately to testing and quarantine.
