| 2015 || || || "In a 2015 study, a team of Indian scientists studied the dispersion of particles expelled during coughing/sneezing using aerodynamic simulation techniques. The study was led by Guruswamy Kumaraswamy, Indian Institute of Technology (IIT) Bombay; Prem Andrade, Ansys Software; and Pankaj Doshi, Pfizer Inc. The researchers observed that larger droplets emitted from coughing/sneezing can be blocked by a mask. A mask reduced the distance travelled by smaller droplets from nearly 2 metres to less than 30 cm. At the same time, maintaining a physical distance of at least 2 metres is greatly beneficial as even the particles that escaped the mask in the study could carry the virus no farther than 1.5 metres."<ref name="indiabioscience.orges"/> ||

The gauze mask had has both practical and performative significance. Practically, it created creates a barrier (however imperfect) against the inhalation of invisible airborne pathogens. At the same time, it performed performs symbolically the idea of a regime against airborne pathogens."<ref name="We share what we exhale"/> ||

| 2018 || || || " A 2018 study by Jin Yan and colleagues from the US Food and Drug Administration constructed a model based on assumptions from laboratory data. They concluded that if only 20 percent of people use masks, it wouldn’t make a difference for the spread of influenza. At 50 percent compliance, though, with the use of high-filtration surgical masks, the effect might be substantial."<ref name="dgyhy">{{cite web |title=The Face Mask Debate Reveals a Scientific Double Standard |url=https://www.wired.com/story/the-face-mask-debate-reveals-a-scientific-double-standard/ |website=wired.com |accessdate=13 September 2020}}</ref> || ||
