And thats fine. But as i said (maybe i missed it since you posted alot and only have time to give it a glance) There arent any Multi-varied analysis done in regards to the mask data, mainly because one there hasnt been enough time to do so and 2 there arent enough data points to analyze yet (takes tens of thousands spread across a wide range of different populations) to say conclusively say that masks reduce infection and if so to what weighted percentage of said reduction. for example lets say we have a data set of 100k that show a reduced infection raet of 10% (not true but just as an example) the we break it down by age group, population density, average ambient air temperature, income, education level etc....lots of other factors but you get my drift. we then calculate infection rates across all other variables. we can then calculate the actual effect by comparing those numbers with the same numbers from one or in this case multiple control groups that masks had in that reduction. the data we have is really leaning toward a much smaller effect than the politicians and media have been telling us i would say within the next 18 months we will see some hard figures coming in. My educated guess is that masks will have some impact on infection rates but nowhere near the impact they are trying to sell us right now.From the WHO in 2019, no evidence masks prevent transmission:
From the cdc:
Straight from the NIH, masks are detrimental to our health..
Facemasks in the COVID-19 era: A health hypothesis
Many countries across the globe utilized medical and non-medical facemasks as non-pharmaceutical intervention for reducing the transmission and infectivity of coronavirus disease-2019 (COVID-19). Although, scientific evidence supporting facemasks’ efficacy is lacking, adverse physiological, psychological and health effects are established. Is has been hypothesized that facemasks have compromised safety and efficacy profile and should be avoided from use. The current article comprehensively summarizes scientific evidences with respect to wearing facemasks in the COVID-19 era, providing prosper information for public health and decisions making.
Keywords: Physiology, Psychology, Health, SARS-CoV-2, Safety, Efficacy
The existing scientific evidences challenge the safety and efficacy of wearing facemask as preventive intervention for COVID-19. The data suggest that both medical and non-medical facemasks are ineffective to block human-to-human transmission of viral and infectious disease such SARS-CoV-2 and COVID-19, supporting against the usage of facemasks. Wearing facemasks has been demonstrated to have substantial adverse physiological and psychological effects. These include hypoxia, hypercapnia, shortness of breath, increased acidity and toxicity, activation of fear and stress response, rise in stress hormones, immunosuppression, fatigue, headaches, decline in cognitive performance, predisposition for viral and infectious illnesses, chronic stress, anxiety and depression. Long-term consequences of wearing facemask can cause health deterioration, developing and progression of chronic diseases and premature death. Governments, policy makers and health organizations should utilize prosper and scientific evidence-based approach with respect to wearing facemasks, when the latter is considered as preventive intervention for public health.
