What does aerosol propagation mean?

Aerosol propagation refers to that fog drops lose moisture in the process of air suspension, leaving a nucleus composed of protein and pathogens, forming a fog drop nucleus, which can float to far places in the form of aerosol, resulting in long-distance propagation. Aerosol transmission may also occur under some special circumstances, such as clinical tracheal intubation and other professional medical operations.

Disinfection is an important means to cut off the route of transmission and control the epidemic situation of infectious diseases, but it should not be excessive. It should be done according to the norms and pay attention to potential risks.

Extended data:

Aerosol particles have the characteristics of uneven distribution, small change scale and complexity, and are mostly concentrated in the bottom of the atmosphere, which plays an important role in the formation of cloud condensation nuclei, raindrops and ice crystals, and then the formation of precipitation. Aerosols can even change the existence time of clouds, produce chemical reactions on the surface of clouds, determine rainfall and affect atmospheric composition. ?

Aerosol particles can affect weather and climate in two ways. On the one hand, it can reflect sunlight into space, thus cooling the atmosphere and making the visibility of the atmosphere worse; On the other hand, it can reduce the escape of long-wave radiation on the ground, and heat the atmosphere through particle scattering, diffusion and absorption of part of solar radiation.
