Risk of viral airborne transmission peaks within 5 seconds of face-to-face encounters

Researchers visualized and measured the flow field of aerosol particles derived from exhaled air and examined the risk of viral exposure during face-to-face encounters, such as while walking, jogging, running, or sprinting. The results showed that the number of aerosol particles during face-to-face encounters peaked within 5 seconds after the encounter and rapidly declined thereafter.
