Background
To reduce the transmission of new coronaviruses and pathogens transmitted by aerial route (e.g. tuberculosis, measles, chickenpox), bioaerosols are currently the main problem of pathogen transmission, bioaerosols being colloidal systems formed by microorganisms suspended in the air, containing bacteria, fungi, mould spores, pollen, dander, allergens, viruses, eggs of dust mite industry parasites, etc. Bioaerosols can be transmitted at a very rapid rate as people cough, sneeze, etc. The novel coronavirus, Beijing plague cases in 2019, Severe SARS (SARS) in half China and influenza abused every autumn and winter (H1N1, H3N2, etc.) were transmitted mainly by aerosal. Water droplets smaller than 5 microns can be suspended in air for minutes to hours because the air resistance is strongly affected with respect to gravity. In addition, virus-laden water droplets evaporate in the air, reducing the volume of the water droplets. Even if most of the liquid evaporates from the droplet with the virus, the droplet does not disappear; it becomes smaller and smaller, and the smaller the water droplet, the longer it takes to suspend in the air. Because droplets of smaller diameter penetrate the pulmonary system more effectively, they also carry a greater risk of infection.
