Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Pathogens are transmitted through respiratory droplets and aerosols, whereas smelling odorous particles involves the detection of volatile chemical compounds, which do not themselves transmit infectious agents.

The analysis

The claim asserts that pathogens are transmitted by smelling odorous particles (volatile compounds). However, scientific understanding establishes that airborne pathogen transmission occurs through physical respiratory droplets and aerosols containing microorganisms, whereas olfactory sensing detects chemical molecules (VOCs). None of the provided papers support the idea that smelling odors causes pathogen transmission; instead, aerobiology studies focus on biological aerosols, droplets, and environmental parameters governing droplet-borne diseases.

Pathogens are transmitted via aerosols and droplets, not through the olfactory perception of odorous chemical molecules (volatile organic compounds) as stated in the claim.
