It is not possible to identify the haze as a medium for the new coronavirus. New coronavirus can form aerosols suspended in the air medium, and its sphere size is mostly between 0.01-10 microns, which are respirable particles that can reach the bronchi and alveoli directly, but transmission can only occur in special locations, such as wards and laboratories with poor air flow. In contrast, haze spheres less than 2.5 microns in diameter have a much greater penetrating power to reach the fine bronchial walls and interfere with gas exchange in the lungs. There is no evidence that smaller diameter haze can transmit the new coronavirus, and the haze is mostly in the outside public space, and even if the virus is transmitted, the concentration is heavily diluted and may not reach pathogenic levels.
