The analysis of the infectious virus showed that a significant number of flu patients routinely shed infectious virus, not merely detectable RNA, into aerosol particles small enough to present a risk for airborne transmission.

This airborne transmission becomes even more prevalent in health-care settings because of overburdened and overcrowded hospitals and the presence of patients with immunosuppression.
Now, most scientists understand that there are significant physical and evolutionary barriers to a blood- and fluid-borne virus developing airborne transmission, as Garrett has acknowledged.
There are different pathways of pathogen transport such as direct contact with an infected person or as airborne transmission or a combination of pathways.
The main route of M genavense infection in the diamond doves was most likely airborne, suggesting a potential zoonotic risk of airborne transmission between humans and birds.
