Airborne transmission of viruses between humans requires specific viral stability and respiratory droplet characteristics
Airborne transmission of viruses is strongly dependent on the physical properties of respiratory droplets, including their initial size, evaporation rates, and environmental conditions such as humidity.
The retrieved literature consistently emphasizes that airborne transmission dynamics rely heavily on droplet characteristics (size, evaporation, composition) and environmental factors (humidity, temperature) which influence viral longevity and dispersion. Therefore, the claim is supported.

Demonstrates how droplet size, viral content, and physical dispersion characteristics dictate airborne transmission risk.

Highlights how temperature and relative humidity primarily determine the longevity of the liquid phase of aerosol droplets and thus transmission pathways.
