This is a correction to: Pratyush K Kollepara, MSc, Alexander F Siegenfeld, SB, Nassim Nicholas Taleb, PhD, Yaneer Bar-Yam, PhD, Unmasking the mask studies: why the effectiveness of surgical masks in preventing respiratory infections has been underestimated, Journal of Travel Medicine, Volume 28, Issue 7, October 2021, taab144, https://doi.org/10.1093/jtm/taab144
In the originally published version of this manuscript, there were errors in in-text references at three points. Citations after the following three passages in text have been changed.
``For small v, the probability of a susceptible individual becoming infected will approach zero, because there is a threshold for the viral dose (the amount of the virus inhaled) below which the probability of infection is very small due to the innate immune system.''
``Concave curves have also been used to model dose response curves, but such an approach ignores threshold effects.''
``For example, a randomized control trial (RCT) at the Hajj pilgrimage''.
This error has been corrected. The publisher apologizes that these errors were not corrected at an earlier production stage.
