❦ The UKHSA’s definition of ‘Airborne’, and how it applies to SARS-CoV-2 / COVID-19:
➲ Airborne (droplet or aerosol) transmission:
‘This occurs when an infected person coughs, sneezes, or talks (droplets) containing the infectious agent are expelled into the air and inhaled by someone nearby OR when an infectious agent is suspended in the air and inhaled by someone (aerosol) because the infectious particles are much smaller and can remain suspended in the air for long periods of time.
For example flu, RSV, COVID-19, TB, measles, C. diphtheria, Strep pneumoniae.’
❂
➲ [Note]: The accepted scientific definition of ‘airborne transmission’ most certainly also includes the act of breathing.
While the UKHSA admits to close-range SARS-CoV-2 transmission via droplet (and aerosol), it neglects to emphasise far-range transmission via infectious aerosols.
