Study: Aerosol Particle Emission Increases Exponentially Above Moderate Exercise Intensity Resulting in Superemission During Maximal Exercise. Image Credit: Kamil Macniak / Shutterstock.com

A major research topic during the ongoing coronavirus disease 2019 (COVID-19) pandemic has been the emission patterns of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). SARS-CoV-2 is mainly transmitted by aerosols produced during breathing, singing, shouting and other common activities. Taken together, these factors play an important role in the transmission of SARS-CoV-2 indoors during … Read more
