The National Institutes of Health has been conducting a study on the spread of the coronavirus through normal conversation. The study has found that someone who is infected could spread the virus through normal indoor talking levels, especially in enclosed spaces. “Aerosols from infected persons may therefore pose an inhalation threat even at considerable distances and in enclosed spaces, particularly if there is poor ventilation,” wrote Harvard University biologist Matthew Meselson. Larger particles can be exposed through coughing or sneezing, but normal breathing and talking can still release these smaller particles that can be carried around the room. However, it appears as though the particles released by talking do not settle on surfaces and then cause infection like the larger ones do.
