Study: Corona Virus Is Able To Spread Through Speech

A study published Wednesday showed that speech generates small particles that can remain suspended in the air in a closed space for more than 10 minutes, highlighting the likely role of these particles in spreading the emerging corona virus.
Researchers at the National Institute of Gastroenterology, Diabetes and Kidney in the United States conducted an experiment in which a person spoke loudly, repeating the phrase “keep your health” for 25 seconds in a closed box.

The laser beams shed on the box showed small particles that could be seen and counted and remained suspended in the air for 12 minutes, according to the study published in the journal “Lecturer of the National Academy of Sciences in the United States of America.”
Given the concentration of the Corona virus in saliva, scientists have estimated that every minute of speaking loudly it can generate more than a thousand particles that contain the virus and are able to remain in the air for eight minutes or more indoors.

And “this direct incarnation shows how normal conversations can generate airborne particles and remain suspended for tens of minutes and prominently able to transmit disease in confined spaces,” the researchers concluded.
The same team noted that speaking with a louder voice generates fewer particles, in research published in the New England Journal of Medicine in April.
And if it is possible to confirm the level of infection capture through speech, this could give a scientific boost to the recommendations to put a muzzle on the face in many countries, and also help in understanding the rapid spread of the virus
