Bjorkman KK, Saldi TK, Lasda E, et al. - This study was undertaken to demonstrate COVID spread, ascertaining transmission rate, and defining factors that increase transmission risk, are essential. Researchers examined longitudinal data of 6,408 students and identified 116 likely transmission events in which a second roommate tested positive within 14 days of the index roommate. This study’s findings demonstrate that inter-roommate transmission occurs infrequently in residence halls and provides strong correlative evidence that viral load is proportional to transmission probability.
