Homemade Masks
Homemade Masks
[Cueball stands at a distance from Megan, who is wearing a face mask] Cueball: Homemade mask, huh? You think they help? Cueball: I've read so many conflicting things.
[Flashback to when Megan was not wearing a mask but carrying a large sign, with Cueball and Ponytail approaching her from both sides. It is not possible to read what is on the sign. Masked Megan is pictured in an inset panel.] Megan (narrating): Well, what I was doing before was carrying around a big sign that said "There's a pandemic so please give me space because I don't want to get sick or make anyone else sick!"
[Same as first panel] Megan: The problem was, I had to write small to fit, so people kept walking closer to read it. Cueball: Oops. Megan: Yeah, the mask gets it across better.

This comic is the 15th comic in a row (not counting the April Fools' comic ) in a series of comics related to the COVID-19 pandemic .
In this comic, Cueball wonders if Megan's 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 N95-class masks or surgical masks , 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.
The title text indicates an alternate method, where Megan could change the sign into a device for pushing people back in order to maintain distance.  Holding the sign out in front of her (instead of over her head) would also let people get close to the sign to read it, without getting in her face.
