COVID-19 Viral Loads, Environment, Ventilation, Masks, Exposure Time, And Severity : A Pragmatic Guide Of Estimates	2020-10-05		.txt	text/plain	5519	272	53	This study uses measured amounts of SARS-CoV-2 in the air of a hospital room with COVID-19 patients from a published and peer-reviewed study and known Influenza A challenge doses from a published and peer-reviewed study and known ASHRAE Office Ventilation standards and an Outdoor Air Exchange model to estimate the time necessary to cause various exposure levels and resulting infection potential in various indoor and outdoor settings of both Influenza A and COVID-19. The estimates in this study also present an initial framework and specific quantitative examples for better understanding of the effects of ventilation on aerosolized transmission, and the immunology related to challenge doses, and the potential for low-level viral load exposure to result in some level of immunity without symptoms of illness (asymptomatic infection).	./cache/cord-282085-r3w90vg8.txt	./txt/cord-282085-r3w90vg8.txt
