In an early-release research letter in the journal Emerging Infectious Diseases, researchers said they found that nine people sitting near one another at a restaurant in China in January got COVID-19, the illness caused by the coronavirus, and that it likely spread because of the restaurant's air-conditioner.
The authors advised restaurants to increase the distance between tables and improve ventilation.
As restaurants look to reopen, experts say they will need to take extra safety measures, such as reducing capacity, having employees wear masks, and capping how long diners can stay there.
