. In Case You’ve Missed It Study finds children release fewer respiratory droplets and aerosols, a clue to understanding Covid-19 transmission « JO LEE MAGAZINE

CNN – For the study, published Wednesday in the Journal of the Royal Society Interface, the researchers studied 15 children between the ages of 8 and 10 and compared the rates at which they emitted particles for various vocal tasks with the emission rates of 15 adults. They measured the number of particles emitted over time as well as the volume of particles emitted over time. According to Linsey Marr, professor of civil and environmental engineering at Virginia Tech, it’s not clear which metric — number or volume of particles — is most important in assessing viral transmission, but experts believe that a higher volume is linked to a higher viral load.
