[Pre-print, not peer reviewed]<\/i> A laboratory experiment simulating a reduced occupancy classroom with aerosolized salt as a surrogate for potential SARS-CoV-2 airborne transmission suggests that good ventilation with up to 10 air exchanges per hour was not enough to achieve an infection probability of less than 1% following exposure for over an hour. However, use of face coverings with moderate to high filtration efficiency by all individuals in the room could reduce infection probabilities to 0.1% or <0.01%.<\/p>\n
