We described the clinical features of people infected on board the Diamond Princess cruise ship who were diagnosed with asymptomatic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection or mild or severe COVID-19, on admission to [...]

Exhaled respiratory particles during singing and talking

By |2020-09-11T02:38:50+00:00September 11th, 2020|

Introduction Choir singing has been suspended in many countries during the Covid-19 pandemic due to incidental reports of disease transmission (Hamner 2020). The mode of transmission has been attributed to exhaled droplets, but with the exception of a study on tuberculosis from 1968, there is presently almost no scientific evidence of increased particle emissions from singing [...]

Obesity, metabolic syndrome tied to risk of COVID infection, severity
