This post gives me a strong sense of deja vous, I'm sure this exact topic was covered early in when they first started with the mask nonsense. It's interesting that the article chose the photos it did. One is a clear photoshop, the other is Awaken with JP doing a satirical skit. While wearing a mask of of no use against an air norm viral infection, there are some big problems with observational studies like this. There is often significant bias in the groups. Perhaps those wearing masks more were in higher risk environments? Though, the biggest confounder was likely a testing bias. People who wore masks are more likely to test more often, leading to a higher rate of positive tests, etc. From the underlying paper: >Bias > >Participants in the study were not randomly assigned to wear or not wear face masks, and they were neither provided with nor encouraged to use face masks. During the study period, official guidelines for face mask use changed, with mandatory use in certain situations. This may have affected the participants’ use of face masks, with some choosing to wear them based on their own assessment of risk and effectiveness. > >Additionally, there may be other factors that could confound the relationship between face mask use and study outcomes, such as participants in high-risk professions or with risk factors for severe COVID-19. Both groups may be more or less prone to wear face masks while also observing different social distancing practices than the average population. We also cannot rule out reverse causality, in which those testing positive for COVID-19 were more prone to wear masks afterwards in order to protect others. **Finally, there could be an association between the inclination to test and the propensity to wear a face mask**
