Masking Study by Denis Rancourt
Do viruses transmit outdoors?
Never confirmed in a controlled scientific study
Inferred from uncontrolled observational studies
The average of these studies suggest 0.5% of transmission could occur outdoors, but these studies don't rule out that transmission may have occurred indoors
