A team of researchers affiliated with several institutions in China has found evidence of hotspots for airborne SARS-CoV-2 RNA at several sites in China. In their paper published in the journal Nature, the group describes collecting air samples from sites in China and what they learned through analyzing them.

Most medical researchers agree that the primary mode of transmission of the SARS-CoV-2 virus is through the expulsion of droplets into the air when infected people cough, or even just breathe. Researchers also believe that the virus can be transmitted through contact with objects in which the virus has come to rest. In this new effort, the researchers sought to learn more about the concentrations of the virus that persist in the air after an infected person has expelled it.

To learn more about viral aerosol persistence, the researchers set up aerosol traps inside and near hospitals that were treating COVID-19 patients in February and March. Some of the sites included hospitals that were treating those who were critically ill, while others were located in field hospitals treating those with less severe symptoms. In all, the team collected 40 samples from 31 sites.
