Study: Loud speech can leave coronavirus in air for up to 14 minutes

Tiny particles escaping from a person’s mouth when they speak loudly – which may contain the coronavirus – can stay in the air from eight up to as much as 14 minutes, a study has found.

The study was published in the Proceedings of the National Academy of Sciences of the United States of America.

The results emphasize the importance of wearing medical masks amid the coronavirus pandemic.
