    Ah a medical expert as I can see. Please go ahead and enlighten me: where is your systemic proof of the ineffectiveness of masks as a precaution to reduce the spread of Covid?

    If it’s not too much to ask, please be so kind to provide the statistics regarding the different severity levels and corresponding number of cases of Covid while comparing that to the common cold.

      From “Physical interventions to interrupt or reduce the spread of respiratory viruses” Jefferson Et Al 2023 Cochrane Database of Systematic Reviews https://doi.org/10.1002/14651858.CD006207.pub6Medical/surgical masks compared to no masks

      We included 12 trials (10 cluster‐RCTs) comparing medical/surgical masks versus no masks to prevent the spread of viral respiratory illness (two trials with healthcare workers and 10 in the community). Wearing masks in the community probably makes little or no difference to the outcome of influenza‐like illness (ILI)/COVID‐19 like illness compared to not wearing masks (risk ratio (RR) 0.95, 95% confidence interval (CI) 0.84 to 1.09; 9 trials, 276,917 participants; moderate‐certainty evidence. Wearing masks in the community probably makes little or no difference to the outcome of laboratory‐confirmed influenza/SARS‐CoV‐2 compared to not wearing masks (RR 1.01, 95% CI 0.72 to 1.42; 6 trials, 13,919 participants; moderate‐certainty evidence)
