The relative importance (cause-specific probability) of aerosol transmission in households in Hong Kong and Bangkok.

<p>The contour lines show the proportion of secondary influenza B virus infections attributed to aerosol transmission in the control arm of each study, under varying assumptions about the efficacy of randomization to the hand hygiene and surgical mask interventions in reducing contact (x-axis) and droplet (y-axis) transmission respectively.</p

Point estimates and 95% credible intervals of model parameters under an exemplar plausible scenario that hand hygiene and surgical face masks reduced contact and droplet transmission respectively by 50% from the time of application of those interventions.

<p>*The forces of infection in combination with a shared shape parameter determine the hazard associated with each competing mode of transmission.
