Aerosol transmission is the spread of new coronavirus infections in healthcare settings with a higher likelihood, such as when patients are intubated and sputum is retained close to the patient, where the potential for aerosol transmission exists in a relatively confined space. Aerosol transmission occurs primarily in medical settings, but there are things that can be done in daily life to prevent aerosol transmission. First of all, we should pay attention to personal mask wearing, hand washing, good personal hygiene and protection, reduce the gathering of people and meals, and now do not advocate the gathering of people in unprotected situations. There are possible conditions to enhance ventilation in confined spaces, maintain good ventilation, whether it is a living room or work environment, this can also reduce the presence of aerosol transmission.
