J Granville-Chapman and R L Dunn review the etiquette of sneezing in surgical masks
Sneezing etiquette and the efficacy of masks in the operating theatre remain a subject of debate. Standard teaching dictates that one must face the wound when sneezing, so that droplets escape backwards, via the sides of the mask. A literature search found no clear demonstration of this principle.
We therefore tested the hypothesis that one should face the wound when sneezing into a surgical mask in theatre.

Our photographs show that the most important visible escape of spray comes from below the mask on to the surgeon’s chest. We therefore recommend that surgeons should follow their instincts when sneezing during operations.Reference
