| Title | "Beyond Six Feet: Respiratory flows and airborne disease transmission" Abstract: We first describe respiratory flows associated with breathing, coughing and sneezing, giving particular attention to both the liquid and gas phases. We demonstrate that the widely implemented 6-foot-rule safety guideline for COVID-19 was based on a physical picture in which the gas-phase was neglected. Consideration of the gas-phase flows makes clear that the range of droplet-borne pathogen may greatly exceed 6 feet, and introduces the possibility of long-range airborne transmission. Evidence is presented that airborne transmission was the dominant mode of transmission of COVID-19. We develop a guideline for mitigating airborne disease transmission that provides a limit for the time spent in indoor spaces with infected individuals. We further demonstrate that carbon-dioxide may serve as a proxy for concentration of airborne pathogen; thus, carbon-dioxide monitoring allows for a real-time assessment of the risk of COVID-19. |
