From: SAfE transport: wearing face masks significantly reduces the spread of COVID-19 on trains
Comparison of how the total number of infections is affected by the proportion of virus contributing to fomite transmission in the absence of a mask (\(p_{s0}\)) (in blue). The lines depict the average, and the shaded region indicates the 95% confidence intervals based on 100+ simulations; a 80% mask coverage, b 100% mask coverage (in orange). Note: for \(p_{s0}=0.2\) and 0.3, there are 200 repeat simulations to capture the stochastic variation
