RE:A question
As per the CDC and Harvard reports: "Most of the "big droplets" travel a mere six feet...but six feet has never been a magic number that guarantees complete protection." The Centers for Disease Control, bases its recommendation on the idea that most "large droplets" that people expel when they cough or sneeze will fall to the ground within six feet. But scientists, having looked at studies of air flow and being concerned about smaller particles called "aerosols," that can remain suspended in the air for up to 3 hours and can also travel far from the source. That's why your local dental offices have been instructed to await for a 3 hour fallow time between patients IF they don't have CLOSED OPERATORIES and MEDICAL GRADE filtration. To confirm, please feel free to inquire with your local dentist regulating body/college on this fact.
