Loud talking can leave coronavirus in air for up to 14 minutes, study says
Droplets from the mouths of people who are talking loudly can linger in the air for up to 14 minutes before disappearing, a new study reveals.
The findings, which were published in the Proceedings of the National Academy of Sciences, could have a big impact on our understanding of COVID-19 and its transmission.
Public health officials know that SARS-CoV-2 and other respiratory viruses are trasmitted via direct contact and when the virus is present in droplets released when someone coughs or sneezes.
Someone's speech also releases oral fluid droplets into the air, so researchers wanted to investigate how many were produced and how long they remain airborne…
One note of caution: The tightly-controlled study did not examine or measure the types of temperature change or air circulation that you would find in almost any real-world environment.
