How to prevent such diseases in public places becomes an irrevocable global problem.

Respiratory tract transmission is the less controllable mode of transmission in all transmission pathways. The WHO and many domestic papers indicate the importance of ventilation for controlling the spread of respiratory tract infection clusters, and in public transport means such as civil aircrafts and trains and closed buildings, natural ventilation cannot be realized or cannot meet the ventilation requirement, and a fresh air system and an air purification circulating system are adopted for forced ventilation.

And people are all horizontally distributed in the space, and if viruses or pollution sources transmitted by droplets and aerosol exist in the upper air inlet, people at the lower air inlet are at risk of infection or pollution. The air flow is increased, and the total concentration of viruses and pollutants in the air is only reduced, so that the infection or pollution cannot be avoided, and air isolation between individuals in the same indoor space cannot be formed. The peculiar smell that pollutants such as sputum, rubbish on ground produced also can pollute the air under the effect of air current and natural diffusion, influences the air quality, forms the risk of infecting.
