Question

A SPEECH ABOUT COVID 19? PLEASE

Answer 1

Answer:

Speaking produces 2,600 droplets per second, which corresponds to an estimated 2.4-12 nanolitres of airborne oral fluid

The novel coronavirus can spread through droplets emitted when an infected person speaks, according to new research on the virus’ alarming efficiency of transmission. So far, public health specialists had focused on coughing and sneezing as the most potential mediums of transmission of SARS-CoV-2.

Now, scientists from the National Institutes of Health (NIH), US, have come up with troubling

new evidence of transmission in confined spaces. They used an intense sheet of highly sensitive laser light to visualize bursts of small-sized droplets produced during repeated spoken phrases. The droplets are too small to be seen, but are large enough to carry pathogens that can linger in the air “for tens of minutes or longer" before shrinking and eventually disappearing.
