How to prevent aerosol transmission of NCP ?

Q1: What is aerosol transmission?

A: Aerosol transmission refers to long-distance transmission of floating droplet nuclei composed of proteins and pathogens coming out from the droplets upon evaporation. The floating nuclei spread in the form of aerosols.

Q2: Can aerosols spread the novel coronavirus?

A: It is theoretically possible but it is yet to be confirmed. The main routes of the virus infection remain respiratory droplets and contact. Aerosol transmission can only take place under certain conditions, such as in a medical operation of tracheal intubation. Currently no evidence has shown the novel coronavirus can be transmitted through aerosol.

Q3: Can wearing a facemask prevent aerosol transmission?

A: Wearing masks helps prevent people from getting infected by airborne respiratory droplets in routine clinical care or daily work and life.

Q4: Can we open windows for ventilation?

A: Usually the novel coronavirus cannot be found in a well-ventilated place. It is recommended to open windows at least twice a day for ventilation.

Q5: How could the general public avoid aerosol infection?

A: 1. Avoid staying in places with poor ventilation.

2. Open windows to let in and out large amounts of air. It helps to dilute the virus concentration and reduce the risk of infection;

3. Wear a mask and do not touch anything in the elevator where the space is relatively small and with poor ventilation.

4. Wash your hands frequently, keep rooms clean, and maintain distance between one another.











1. 尽量避免前往密闭空间;

2. 自然通风的通风量很大,开开窗,病毒稀释到一定程度,风险就很低了;

3. 电梯间通风很差,又是小空间,一定要戴口罩、小心触摸;

4. 勤洗手、勤擦洗、与他人隔开距离。
