Analysis of Novel Coronavirus Transmission and Comprehensive Prevention and Control Technology Tongji University Shen Jinming Liu Yanmin Abstract Given the discussion on whether the novel coronavirus is transmitted through close-range droplets or airborne transmission, this article analyzes the transmission mode of the novel coronavirus from an engineering perspective based on aerosol mechanics. It is believed that there should also be aerosol cloud transmission between the two. This is a controversial new topic. If the aerosol cloud transmission theory is used to understand various cases in the epidemic, a very reasonable explanation can be obtained, and our control strategy will become very clear. The new transmission mode will also have a series of impacts on intervention measures and personal protection.
