Infected after 5 minutes, from 20 feet away: South Korea study shows coronavirus’ spread indoors

South Korean Dr. Lee Ju-hyung has largely avoided restaurants in recent months, but on the few occasions he’s dined out, he’s developed a strange, if sensible, habit: whipping out a small anemometer to check the airflow in the establishment.

It’s a precaution he has been taking since an experiment in June where he and colleagues re-created the conditions at a restaurant in Jeonju, a city in the southwest, where diners contracted the coronavirus from an out-of-town visitor. Among them was a high school student who became infected after five minutes of exposure from more than 20 feet away.

The results of the study, for which Lee and other epidemiologists enlisted the help of an engineer who specializes in aerodynamics, were published last week in the Journal of Korean Medical Science. The conclusions raised concerns that the widely accepted standard of six feet of social distance may not be far enough to truly keep people safe from COVID-19.
