Propagation of Mouth-Generated Aerosols in a Modularly Constructed Hospital Room

Modular construction methods have been widely used in the civil engineering industry due to ease of assembly, the convenience of design, and allowing for flexibility in placement while making the construction more sustainable. With the increasing number of COVID-19 cases, the capacity of the hospita...
