By relating the predicted median n for a reference scenario to other locations, a Relative Exposure Index (REI) is established that reduces the need to understand the infection dose probability but is nevertheless a function of space volume, viral emission rate, exposure time, occupant respiratory activity, and room ventilation. A 7 h day in a UK school classroom is used as a reference scenario because its geometry, building services, and occupancy have uniformity and are regulated. Xsplit alternative for macThe REI is used to highlight types of indoor space, respiratory activity, ventilation provision and other factors that increase the likelihood of far field ( 2. Scenarios involving high aerobic activities or singing have REI 1; a 1 h gym visit has a median REI 1. Skagit Choir superspreading event has REI 12.
