Yep. Zero evidence. From the CDC web-site: "In our systematic review, we identified 10 RCTs that reported estimates of the effectiveness of face masks in reducing laboratory-confirmed influenza virus infections in the community from literature published during 1946–July 27, 2018. In pooled analysis, we found no significant reduction in influenza transmission with the use of face masks (RR 0.78, 95% CI 0.51–1.20; I2 = 30%, p = 0.25) (Figure 2). One study evaluated the use of masks among pilgrims from Australia during the Hajj pilgrimage and reported no major difference in the risk for laboratory-confirmed influenza virus infection in the control or mask group (33). Two studies in university settings assessed the effectiveness of face masks for primary protection by monitoring the incidence of laboratory-confirmed influenza among student hall residents for 5 months (9,10). The overall reduction in ILI or laboratory-confirmed influenza cases in the face mask group was not significant in either studies (9,10). Study designs in the 7 household studies were slightly different: 1 study provided face masks and P2 respirators for household contacts only (34), another study evaluated face mask use as a source control for infected persons only (35), and the remaining studies provided masks for the infected persons as well as their close contacts (11–13,15,17). None of the household studies reported a significant reduction in secondary laboratory-confirmed influenza virus infections in the face mask group (11–13,15,17,34,35). Most studies were underpowered because of limited sample size, and some studies also reported suboptimal adherence in the face mask group." https://wwwnc.cdc.gov/eid/article/26/5/19-0994_article?fbclid=IwAR21FVILWjj0MqCV2j1OgspKcglxt1CXJmG_zZSiGD8bwo1IIwa5ORFew7k |

Wow. Way to focus on on paragraph and not the conclusion of the study, which is specifically referring to the flu. This is not the flu we are discussing here! Transmission with this is different.
From your article you posted: "It is essential to note that the mechanisms of person-to-person transmission in the community have not been fully determined. Controversy remains over the role of transmission through fine-particle aerosols (3,46). Transmission by indirect contact requires transfer of viable virus from respiratory mucosa onto hands and other surfaces, survival on those surfaces, and successful inoculation into the respiratory mucosa of another person. All of these components of the transmission route have not been studied extensively. The impact of environmental factors, such as temperature and humidity, on influenza transmission is also uncertain (47). These uncertainties over basic transmission modes and mechanisms hinder the optimization of control measures." And: "In lower-income settings, it is more likely that reusable cloth masks will be used rather than disposable medical masks because of cost and availability (38). There are still few uncertainties in the practice of face mask use, such as who should wear the mask and how long it should be used for. In theory, transmission should be reduced the most if both infected members and other contacts wear masks, but compliance in uninfected close contacts could be a problem (12,34). Proper use of face masks is essential because improper use might increase the risk for transmission (39). Thus, education on the proper use and disposal of used face masks, including hand hygiene, is also needed." Also your statement "zero evidence masks work" is the dumbest and most tone deaf comment ever.

I focused on the paragraph that evaluated the effectiveness of masks in preventing transmission. It noted that, in all the medical literature there have been ten randomly controlled trials and not one of them showed any benefit from wearing masks.
That is true. However the viruses are similar in size, present in the same parts of the respitaory system and therefore are very likely to spread similarly. You are correct that it remains a possibility, although a remote one, that there is a significant enough difference that covid spread can be reduced by masks in a way that 'flu is not. However - per my comment - there is as yet zero evidence for that.
These are statements about possiblities, not evidence. The links you provide again contain all sorts of statements, but lack any evidence. One of your links does eventually provide a study which shows that cloth masks lead to greater rates of transmission than medical masks but concludes "Owing to a very high level of mask use in the control arm, we were unable to determine whether the differences between the medical and cloth mask arms were due to a protective effect of medical masks or a detrimental effect of cloth masks." The fact remains that the only actual experiments which have been run (ten of them) have failed to show any effect from wearing masks.
No it's not. It's accurate. There is zero evidence that masks work. That does not mean that it is impossible that masks help. It just means that there is no scientific evidence currently available to us that they do. However the fact that ten separate studies have failed to find any positive effect implies that it is quite likely (although I agree not certain) that they don't provide much of an effect if they provide any at all. |

Does anyone think they’re going to convince anyone of anything they don’t already believe at this point?
Back on topic, PPA does not require masks in the first hour of practice, but requires when they start scrimmaging at the end. |

and back to soccer....
On the same topic do kids that have to wear masks during an entire practice complain or rather not play? My younger DS asked if he could keep his on the entire time...I didnt think it would be an issue and suspect he would just take it off during playing at some point. |

My son's mask got pretty soaked during his practice, so the next time we gave him a spare to wear at the water break, and he has been fine since then. No complaints. I imagine the vast majority of complaints come from parents, and not the kids. |

Ha I asked my DS if he would play with a mask on...He said no. I asked what if he would do if couldn't play without it what would he do. He said he would wear it...lol |

| Bethesda had full length scrimmages this past weekend, wearing masks entire time. Sucks, but they all got through it just fine. |
