Diners should avoid talking while eating in restaurants, South Korean researchers have warned, after finding that COVID-19 can be transmitted more than six metres away.

The study also recommends that indoor venues should also fit a "wind partition" between customers or put them in separate rooms to reduce infection risk.

Researchers made their findings after examining a cluster of cases at a restaurant in Jeonju, South Korea, earlier this year.

Following scrutiny of CCTV images, contact tracing interviews and mobile phone location data, they found that one patient had been infected at a distance of 6.5 metres despite only being exposed for five minutes.

Another was infected at a distance of 4.8 metres after 15 minutes' exposure.

Neither had any direct or indirect contact with the original case.

But despite several other diners in the same restaurant being nearer to the source of the outbreak, several other people were not infected.

The scientists also found the restaurant's ceiling-type air conditioners carried coronavirus droplets over greater distances.

"Droplet transmission can occur at a distance greater than two metres if there is direct air flow from an infected person," the authors of the study wrote in the Journal of Korean Medical Science.

"Therefore, updated guidelines involving prevention, contact tracing, and quarantine for COVID-19 are required for control of this highly contagious disease."

The researchers also said diners should avoid talking in the restaurants to reduce risk of infection.

"In indoor settings such as restaurants, masks should be removed only during meals and should be worn before and after eating, while conversation during meals and loud talking or shouting should be avoided," they add.

The study was published in the Journal of Korean Medical Science.
