A new study by a National University of Singapore (NUS) team has found that an infected person can spread Covid-19 by exhaling fine aerosol particles when breathing, talking and singing, not just though droplets when coughing or sneezing.

Prof Tambyah noted that swab samples from two of the 22 patients had such high viral loads that their samples accounted for half the total amount of virus collected in the study.

This was despite the fact that all the participants had low CT (cycle threshold) values, which would presumably signal high viral loads in their diagnostic swab tests.
