It has recently become “common wisdom” that the wearing of cloth masks (so-called non-medical masks) reduces transmission of the COVID-19 virus. I’ve spent way too much time trying to find scientific research that demonstrates through actual studies that cloth masks reduce transmission of viruses (especially COVID-19). Given that the use of cloth masks began to be advocated during the Spanish Flu pandemic, actual measured, reported, and peer-group reviewed studies showing benefits should be numerous – the absence (silence) of published studies only serves to underscore that no such benefit results from the wearing of non-medical masks.
The inadequate thought experiments mask advocates use to support their advocacy is basically, “When I breath or cough into a piece of cloth, the cloth becomes damp; so, it must be filtering out the virus.” A more rigorous experiment would be to take individuals who are known to be infectious and have them breath without a cloth mask, then capture the air and measure the virus load in that sample. Then repeat with various mask types and at various distances from the test subject. I would think that this experiment could be planned, executed, published, and replicated by others, all in very short order. The fact that no one has bothered to publish the results of such an experiment once again can only cause me to conclude that no benefit is demonstrated.
Hand-washing and distancing have demonstrated results. A cloth mask cannot replace these measures. What I observe around me is that those wearing cloth masks treat the masks as a super-power and as a result stop distancing. I can only assume that that they also stop diligent hand-washing.
