While prior research (e.g. Biasin et. al 2021) has found that UV light is effective in inactivating Covid-19 in controlled laboratory conditions, Knight Campus scientists are the first to attempt a large scale study of this effect “in the wild”.
A large sample of test subjects were recruited using the guise of attending a track meet in Eugene Oregon. The excitement of the track events ensured cheering and yelling – activities known to increase viral transmission. Subjects were assigned seats at varying distances from the UV light (as shown in figure A) to ensure variation in the treatment effect.
Subjects were not individually tested prior to the event, but urine and feces were collected from restrooms to estimate initial viral load. The effectiveness of UV exposure will be determined as subjects are identified in post-meet hospital admissions and names are compared with the HayWard Field seating chart.
