What is aerosol propagation ?
aerosol refers to a gaseous dispersion system composed of solid or liquid particles suspended in a gas medium.
Aerosol is like smoke produced by smoking, suspended in the air and will not dissipate for a long time. Sometimes, even if you can't see it, you can smell the smell of smoke. This is why.
According to experts, "When people cough, spit or sneeze, they discharge liquids or droplets containing many bacteria and viruses from the body, including respiratory infectious diseases such as the new coronavirus pneumonia. Sputum and some large particles of droplets will settle on objects, human bodies or the ground, and some small particles of droplets will be suspended in the air to form aerosols. If a person inhales aerosol produced by coughing, sputum or sneezing in a certain case, an infection may occur. ”
A small mouthful of sputum may cause the spread of the disease. To prevent and control the epidemic, we need to pay attention to coughing etiquette, not spit anywhere, and maintain good hygiene habits.
