Creating a Covid-19 Secure Dining Experience

The risk of COVID-19 transmission significantly increases in indoor settings. Dining areas in restaurants are the prime example of such an indoor setting. One such outbreak occurred in a restaurant in Guangzhou, China on 24th January 2020. Close prolonged contact between numerous people in an enclosed space significantly affected the rate of virus cross infected.


Transmission risks at dining areas depend on the factors such as ventilation strategies, layout, occupancy levels etc. However, risk mitigation in a restaurant on an ongoing basis can be challenging due to the close social proximity of diners. Moreover, the strategies should also be considerate of the occupancy levels to maximise cash flow while also minimising the associated risks
