 This research paper examined the transmission of respiratory pathogens, such as mycobacterium tuberculosis and severe acute respiratory syndrome coronavirus 2, in healthcare settings. The authors found that longer wait times were associated with earlier arrival, being female and having children present. Additionally, they noted that occupancy of waiting rooms varied significantly between rooms and throughout the day. This suggests that light touch estimation of occupancy density could be helpful for guiding interventions to improve patient flow. This article was authored by Aaron S.
