Earlier this year, two diners at a South Korean restaurant were infected with novel coronavirus in a matter of minutes from a third patron who sat at least 15 feet away from them. The third patron was asymptomatic at the time. After dissecting that scene from June, South Korean researchers released a study last month in the Journal of Korean Medical Science that suggests the virus, under certain airflow conditions, travels farther than six feet and can infect others in as little as five minutes.
