In this comic, Cueball wonders if Megan's {{w|cloth mask|homemade mask}} will be of any use, because he has seen many different points of view and is unsure which one is correct.  It is generally agreed that homemade masks will not block particles (including droplets which carry viruses) as effectively as officially-tested {{w|N95 mask|N95-class masks}} or {{w|surgical mask}}s, and possibly confer no benefit at all; however, wearing a homemade mask may reduce contagiousness if the ''wearer'' is infected, by blocking droplets from being expelled.  It may also make the wearer less likely to touch their face (which may be a vector for catching COVID-19 from contaminated surfaces).  On the other hand, there are concerns that it may confer a false sense of security, leading to unsafe behaviors, and that the warm, moist environment produced by the wearer's breath may also ''harbor'' incoming viruses, which may later infect the wearer if the mask is not washed frequently.

Megan replies that she originally carried a sign warning people to keep their distance, but people needed to get close to her to read it, making it counterproductive.  The implication is that Megan's primary purpose in wearing the mask is to signal to other people that's she's concerned about spreading COVID-19, and remind them to keep their distance. Whether or not the mask has any direct benefits in blocking virus transmission, Megan apparently feels that the social impact of seeing someone in a face mask is likely to change behaviors, making transmission less likely.
