The testing station would be a walk through that tests the air for airborne viruses. It would be WiFi linked to a database of viruses that it can scan to find the exact virus type.

Once a virus is detected then ultraviolet lights do a blast over the body to eliminate the virus. The station will have solar cells to collect energy from the lights to lower the electrical usage plus help charge battery backups in case of power failure.

If there were many of these testing stations over time it could show hotspots and also reduce the infections rate by killing viruses that are attached to our bodies.

Over time it could test even if nobody went through it just the air flow and catch viruses even before a human body catches it. Thus alerting the medical staff nearby about a possible outbreak early.
