Thanks to the Heising-Simons foundation for their support: https://www.hsfoundation.org (their COVID-19 grants: https://www.hsfoundation.org/grants/covid-19-response-grants/ )Check out https://aatishb.com/maskmath to explore and for references.This video is about how masks (whether surgical, or N95, or cloth) are counterintuitive and actually work much better epidemiologically than one might expect. Masks do double-duty, and the fraction of interactions with masks is much higher than the fraction of people wearing masks, so partially adopted, partially effective masks are able to reduce the basic reproduction number surprisingly well.REFERENCES:Aatish’s detailed writeup on github: https://github.com/aatishb/maskmath/blob/master/model/mathmodel.ipynbAmid the Coronavirus Crisis, a Regimen for Re-entry: https://www.newyorker.com/science/medical-dispatch/amid-the-coronavirus-crisis-a-regimen-for-reentryFace Masks Against COVID-19: An Evidence Review https://www.preprints.org/manuscript/202004.0203/v3Mask FAQ Test Results: https://www.maskfaq.com/test-resultsThe Effect of Mask Use on the Spread of Influenza During a Pandemic: https://onlinelibrary.wiley.com/doi/full/10.1111/j.1539-6924.2010.01428.xCalibrated Intervention and Containment of the COVID-19 Pandemic: https://arxiv.org/ftp/arxiv/papers/2003/2003.07353.pdfCloth Mask Breathability and Filtration Efficiency Technical Report: https://static1.squarespace.com/static/5e8126f89327941b9453eeef/t/5f2c4463a5c9f75a38d2b26f/1596736614213/N95DECON_cloth_mask_breathability_filtrationtechnical_report_v1_200804.pdfWhat kind of mask should I be wearing to protect against COVID-19? http://built-envi.com/what-kind-of-mask-should-i-be-wearing-to-protect-against-covid-19/Masks for all?
