A personal note: I am using the term virus instead of exosome to avoid causing cognitive dissonance.
No Clinical Virological research since 1933 has been able to demonstrate or prove a link between a virus and contagion. Not One.
Viruses cannot enter through the skin or eyes.

Such vectors do not work because the mucus membranes and the immune system discard small amounts of foreign proteins such as viruses. Viruses cannot enter through wounds because we bleed outwardly not inwardly. Viruses do not exist outside of petri-dish solutions or a living body

Viruses cannot function without a host cell that manufactures them and encodes them, and viruses cannot replicate without a host cell. Viruses do not infect or invade cells. They are not alive to do so in the first place. Viruses almost never dissolve living tissue,

unless in specific circumstances such as polio and degenerative nervous system diseases where metal toxicity is present. Viruses’ primary function is to dissolve dead matter. Cells produce different viral strains depending on the condition of the tissue involved.

There are 320,000 viral strains inherent to the human body, and each cell contains the viral protein makeup to manufacture each strain when the body calls for it. Viruses are sequenced/encoded by blood cells via RNA/DNA to break down specific dead and dying tissue and waste.

Virusesexosomes are quite specific protein structures. Coughing, sneezing, and spitting is not a vector for the transmission of viruses. Saliva and mucus membranes break down any such particles. Skin is not a vector either because viruses cannot cross dead skin layers.

The only way to get a virus outside of natural means is via direct injection (vaccine) or blood transfusions of a patient who has a virus However in such cases the body only analyzes it as foreign tissue that must be eliminated. Cue the sound of pennies dropping and bells ringing
