“I Pity the Fool” said Mr T.Masks work. COVID is airborne. Research has shown that acknowledged the efficacy of mask-wearing to some degree at slowing the spread of COVID-19. A February 2021 article published by the Journal of the American Medical Association reviewed data from 10 previous studies conclude mask wearing substantially reduces spread. A cloth mask reduces exhaled droplets by 50 to 70%. So cloth masks are best at source control but not at filtering the virus itself.
Universal mask adoption for people when in public is recommended by the authors of the “An evidence review of face masks against COVID-19,” first published in January by Proceedings of the National Academy of Sciences of the U.S. Researchers poured over at least 150 other studies, models and findings to draw their conclusion: “The available evidence suggests that near-universal adoption of non-medical masks when out in public, in combination with complementary public health measures, could successfully reduce virus reproduction levels to below 1, thereby reducing community spread if such measures are sustained.” Additionally, they concluded that mask wearing mandates could add $1 trillion to the U.S. GDP by preventing business closures.
A June 2020 University of Iowa study published in the Health Affairs medical journal estimated over 200,000 COVID-19 cases were prevented in May after masking was mandated in several states. For this experiment, researchers used data analysis and models to measure community spread before and after a mask mandate was enacted. Data found that within 1-5 days after a mandate was issued, daily case rates dropped nearly one percentage point. Within 21 or more days, they dropped two.
Face masks, worn correctly, that’s right chin straps don’t count, combined with other preventive measures, such as getting vaccinated, frequent hand-washing and physical distancing, can help slow the spread of the virus that causes COVID-19. The tools are simple and effective, but Americans are. lets face the facts, ignorant fools.
