Table 3. Estimates of within-household transmission parameters.

Parameter estimates are shown for the variable infectivity model with separate child-to-child transmission (cf. Table 2). Estimates are represented by posterior medians and 2.5% and 97.5% posterior quantiles, and are based on 1,000 samples from the posterior distribution. Notice that the introduction hazard parameters of children and adolescents are relative to the introduction hazard in adults (cf. Fig 2).

Parameter	Estimate	95%CrI
Transmission rate among adults (β) (per person per infectious period)	0.13	(0.059-0.22)
Infectiousness of children relative to adults (fC)	2.4	(1.4-5.9)
Infectiousness of adolescents relative to adults fA	0.85	(0.076-3.9)
Transmission rate among children (ζC) (per person per infectious period)	0.97	(0.51-1.7)
Relative introduction hazard of children compared to adults	0.62	(0.34-1.0)
Relative introduction hazard of adolescents compared to adults	0.97	(0.52-1.7)
