A computational model for predicting changes in infection dynamics due to leakage through N95 respirators

Scientific Reports, 2021
In the absence of fit-testing, leakage of aerosolized pathogens through the gaps between the face and N95 respirators could compromise the effectiveness of the device and increase the risk of infection for the exposed population.

MERS-CoV, surgical mask and N95 respirators [PDF]

Singapore Medical Journal, 2014
Dear Sir, The recent article, “Debate on MERS-CoV respiratory precautions: surgical mask or N95 respirators?” by Chung et al(1) is an interesting read. Indeed, the control of this new emerging infection is a topic that is currently under discussion worldwide,(2) and the efficacy of the respiratory protective apparatus is certainly an important issue.
