Table 1. Parameter estimates for the model of modes of transmission.

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.

Parameters	Hong Kong (275 households with 822 contacts)	Bangkok (507 households with 1,266 contacts)
	Estimate (95% CI)	Estimate (95% CI)
φ Shape of the Weibull distribution	1.41 (1.05, 1.79)	1.38 (1.14, 1.61)
λ1 Force of contact transmission*	0.16 (0.01, 0.41)	0.17 (0.01, 0.32)
λ2 Force of droplet transmission*	0.11 (0.00 0.30)	0.13 (0.01, 0.28)
λ3 Force of aerosol transmission*	0.28 (0.07, 0.42)	0.22 (0.11, 0.32)
π1 Risk of fever plus cough for infections by contact route	22% (1%, 51%)	26% (1%, 66%)
π2 Risk of fever plus cough for infections by droplet route	23% (1%, 58%)	33% (2%, 73%)
π3 Risk of fever plus cough for infections by aerosol route	53% (33%, 92%)	77% (55%, 98%)
θ1 Proportion of household adults immune/not exposed	88% (84%, 91%)	74% (71%, 78%)
θ2 Proportion of household children immune/not exposed	80% (72%, 88%)	69% (61%, 76%)

^*The forces of infection in combination with a shared shape parameter determine the hazard associated with each competing mode of transmission. The relative contribution of each mode j is calculated as the cause-specific probabilities ${\lambda }_j^{\phi }/\left({\lambda }_1^{\phi }+{\lambda }_2^{\phi }+{\lambda }_3^{\phi }\right)$.
