Modeling the Transmission of Covid-19. Journal of Public Health Management and Practice
A transmission model of a pre-K-12 US school setting found that even in the context of low community incidence of SARS-CoV-2, mitigation strategies and contact tracing with a net effectiveness of 27% could result in 75% of the school population being infected within 6 months. The model is based on the CDC COVIDTracer modeling tool….

Strategies to Minimize SARS-CoV-2 Transmission in Classroom Settings Combined Impacts of Ventilation and Mask Effective Filtration Efficiency
[Pre-print, not peer reviewed] A laboratory experiment simulating a reduced occupancy classroom with aerosolized salt as a surrogate for potential SARS-CoV-2 airborne transmission suggests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…
