Another fascinating study on the perils of indoor dining, this time from South Korea.

In this case, a single person infected two others, one of them being 6.5 meters away and in the same room as the infected person for only five minutes.

What’s particularly fascinating about this study is the lengths that the researchers went to confirm the chain and method of infection; making use of CCTV, personal location data, and even computer modelling of the airflow inside the restaurant.

Whilst this research throws some doubt on the usefulness of the two-meter distance rule; it reinforces that rapid airflow is essential and that being in an indoor setting without a mask for any length of time puts you at increased risk of infection.

There’s a great write-up of the study here.
