COVID-19 experiment with human guinea pigs
"The experiment involved 2,000 concertgoers, who were mostly young, healthy and not belonging to any high-risk group. Attendees had to provide a negative COVID-19 test result prior to the concert and their temperature was taken upon arrival at the venue. They wore FFP2 face masks during the event and were fitted with contact-tracing devices, which would complement sensors on the ceiling of the venue that collected data on their movements. "We want to study how much contact the participants have with one another during the concert - which is actually still not clear," research lead Stefan Moritz said. Fluorescent disinfectant was also distributed. "After the event, we can see with ultraviolet lamps which surfaces glow in particular, meaning they were touched particularly often," Moritz added. Halle scientists also tracked the movement of aerosols; the smallest particles in the air that can carry the virus." https://www.dw.com/en/german-scientists-run-conc...
