The airborne contagiousness of respiratory viruses:A comparative analysis and implications for mitigation
文献摘要：
The infectious emission rate is a fundamental input parameter for airborne transmission risk assessment,but data are limited due to reliance on estimates from chance superspreading events.This study assesses the strength of a predictive estimation approach developed by the authors for SARS-CoV-2 and uses novel estimates to compare the contagiousness of respiratory pathogens.We applied the approach to SARS-CoV-1,SARS-CoV-2,MERS,measles virus,adenovirus,rhinovirus,coxsackievirus,seasonal influenza virus and Mycobacterium tuberculosis(TB)and compared quanta emission rate(ERq)estimates to literature val-ues.We calculated infection risk in a prototypical classroom and barracks to assess the relative ability of ventilation to mitigate airborne transmission.Our median standing and speaking ERq estimate for SARS-CoV-2(2.7 quanta h-1)is similar to active,untreated TB(3.1 quanta h-1),higher than seasonal influenza(0.17 quanta h-1),and lower than measles virus(15 quanta h-1).We calculated event reproduction num-bers above 1 for SARS-CoV-2,measles virus,and untreated TB in both the classroom and barracks for an activity level of standing and speaking at low,medium and high ventilation rates of 2.3,6.6 and 14 L per second per person(L s-1 p-1),respectively.Our predictive ERq estimates are consistent with the range of values reported over decades of research.In congregate settings,current ventilation standards are unli-kely to control the spread of viruses with upper quartile ERq values above 10 quanta h-1,such as SARS-CoV-2,indicating the need for additional control measures.
