Guideline to limit indoor airborne transmission of COVID-19: Study ANI | Updated: Apr 16, 2021 05:20 IST
Washington DC [US], April 16 (ANI): A recent study has reported a safety guideline to limit airborne transmission of COVID-19 that goes beyond the six-foot social distancing guideline.
The safety guideline imposes an upper bound on the time spent in an enclosed space that is developed by considering disease infectivity inferred from case studies of indoor spreading events, rates of ventilation and air filtration, room dimensions, number of occupants, breathing rates, respiratory activity, and occupants face mask use, according to the authors.
By assuming that the respiratory droplets are mixed uniformly through an indoor space, the study derive a simple safety guideline for mitigating airborne transmission that would impose an upper bound on the product of the number of occupants and their time spent in a room.
A new approach to estimate the risks of exposure to COVID-19 under different indoor settings
Two MIT professors have proposed a new approach to estimating the risks of exposure to Covid-19 under different indoor settings.
The guideline they developed suggests a limit for exposure time, based on the number of people, the size of the space, the kinds of activity, whether masks are worn, and the ventilation and filtration rates. Their model offers a detailed, physics-based guideline for policymakers, businesses, schools, and individuals trying to gauge their own risks.
The guideline, appearing this week in the journal
PNAS, was developed by Martin .Z. Bazant, professor of chemical engineering and applied mathematics, and John W. M. Bush, professor of applied mathematics. They stress that one key feature of their model, which has received less attention in existing public-health policies, is providing a specific limit for the amount of time a person spends in a given setting.
