Talking, Singing May Help Transmit COVID-19

A new study led by researchers from the National University of Singapore (NUS), and conducted at the National Centre for Infectious Diseases (NCID), revealed that severe acute respiratory syndrome coronavirus (SARS-CoV-2) particles can be aerosolised by an infected person during talking and singing. They also found that fine aerosols (less than 5 micrometres, or μm) generated from these two types of activities contain more viral particles than coarse aerosols (more than 5 μm).
