Advanced! Beijing Winter Olympics will test nucleic acid in the air | Tutu Science Fiction

Q

Can’t tell the difference between aerosols and droplets?

A

Droplets refer to the liquid sprayed from the mouth when people talk or sneeze. They are liquid particles with a diameter generally larger than 5 microns and fall to the ground within eight meters. Aerosols refer to all solid and liquid particles suspended in the air with a smaller diameter and may be blown hundreds of meters by the wind. In general, both droplet transmission and aerosol transmission should be taken seriously. Pay attention to personal protection, wash hands frequently, ventilate frequently, disinfect frequently, and do not take off masks casually in confined spaces.
