In the guidelines for the diagnosis and treatment of novel coronavirus pneumonia, the transmission route of aerosols is particularly emphasized. Aerosols become an important mode of transmission of novel coronaviruses because they are suspended in tiny particles in a closed environment, which is a potential mode of transmission of novel coronaviruses. This mode of transmission is different from the droplet and close contact transmission originally emphasized. In the case of aerosol transmission, the virus-containing aerosol may remain in the confined environment for a long period of time due to the fact that the confined environment cannot be easily ventilated, and if a person inhales the virus-containing aerosol, he or she may be infected with the novel coronavirus. So this is one of the ways that is now considered highly likely to be an important route of transmission of the novel coronavirus. It’s getting more and more attention now, but this mode of transmission can be prevented, such as by minimizing the potential threat of aerosols by wearing airtight masks or by washing hands frequently and paying attention to ventilation.
