研读了这篇文献,如果单纯说呼吸产生了气溶胶,这篇文献没问题。但此气溶胶已经不是流行病学意义上的气溶胶了,您可以对比一下这篇文章:
Recognition of aerosol transmission of infectious agents: a commentary
Raymond Tellier1, Yuguo Li2, Benjamin J. Cowling3 and Julian W. Tang4,5*
Abstract
Although short-range large-droplet transmission is possible for most respiratory infectious agents, deciding on whether
the same agent is also airborne has a potentially huge impact on the types (and costs) of infection control interventions
that are required.
The concept and definition of aerosols is also discussed, as is the concept of large droplet transmission, and airborne
transmission which is meant by most authors to be synonymous with aerosol transmission, although some use the term
to mean either large droplet or aerosol transmission.
However, these terms are often used confusingly when discussing specific infection control interventions for individual
pathogens that are accepted to be mostly transmitted by the airborne (aerosol) route (e.g. tuberculosis, measles and
chickenpox). It is therefore important to clarify such terminology, where a particular intervention, like the type of personal
protective equipment (PPE) to be used, is deemed adequate to intervene for this potential mode of transmission, i.e. at
an N95 rather than surgical mask level requirement.
With this in mind, this review considers the commonly used term of ‘aerosol transmission’ in the context of some infectious
agents that are well-recognized to be transmissible via the airborne route. It also discusses other agents, like influenza virus,
where the potential for airborne transmission is much more dependent on various host, viral and environmental factors,
and where its potential for aerosol transmission may be underestimated.
