Since the pandemic, the world has recovered to the point where social gatherings are no longer restricted, especially in public spaces like restaurants and bars. This comprehensive review looks at previous investigative airborne transmission studies in indoor settings to identify gaps in current literature and recommend changes in approach for indoor airborne transmission research.

It was found that very few airborne transmission studies exist in social settings like restaurants. Additionally, it was observed that speech is not considered a major respiratory activity responsible for airborne transmission. The main recommendation is to improve the prediction of indoor flows, which can help predict the risk better and, in the end, minimize airborne transmission. That is precisely what Arghyanir Giri, Clara García-Sánchez, and Philomena Bluyssen, researchers from TU Delft, aim to do in collaboration with the PDPC.
