Shared Children's Bedrooms May Pose High Risks of Airborne Influenza A Virus and Rhinovirus Transmission: A Simulation Study

higher for H3N2 and H1N1 infection risks, respectively. A plume formed from the infected individuals exhaled breath to the susceptible individual's face, which may explain, in part, the high risks estimated. While settings for tidal breathing did not disrupt the formation of this plume, increased air exchange rate did. Respiratory viral infection risks can be high in shared bedroom scenarios, especially with low fresh air ventilation and alignment of furniture such that plumes can form between the faces of individuals.
