Do Masks Do Any Good?

This study on the CDC website evaluated the effectiveness of hand cleaning procedures and use of the surgical masks that we are supposed to be using for COVID-19.   In this study they were checking for effectiveness against influenza.  These are two similar sized viruses. 

Nonpharmaceutical Measures for Pandemic Influenza in Nonhealthcare Settings—Personal Protective and Environmental Measures

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)...

Disposable medical masks (also known as surgical masks) are loose-fitting devices that were designed to be worn by medical personnel to protect accidental contamination of patient wounds, and to protect the wearer against splashes or sprays of bodily fluids (36). There is limited evidence for their effectiveness in preventing influenza virus transmission either when worn by the infected person for source control or when worn by uninfected persons to reduce exposure. Our systematic review found no significant effect of face masks on transmission of laboratory-confirmed influenza.

They did not look at

Respirators (N95) because they require a fit level not usually achieved and not likely available in sufficient quantity for an influenza pandemic.  Perhaps this is why Fauci initially argued against masks. 

There are listed reasons why the experiments were perhaps not very effective tests, so as annoying as they are, we should probably keep using them for the moment to humor our supposed betters.  At some point they will either call the All Clear or they will eventually face pitchforks and torches.
