Model descriptions and deviance information criterion.

	FOI assumption	Description	DIC
Model A	${\lambda }_y^C={\lambda }_y^Y={\lambda }_y^A$	Age-constant and time-varying FOI.	18,165
Model B	$\left({\lambda }_y^C={\lambda }_y^Y\right)\ne {\lambda }_y^A$	Age- and time-varying FOI, with the assumption that FOI among 5–14-year-olds is equal to the FOI for 0–4-year-olds.	15,139
Model C	${\lambda }_y^C\ne \left({\lambda }_y^Y={\lambda }_y^A\right)$	Age- and time-varying FOI, with the assumption that FOI among 5–14-year-olds is equal to the FOI for those 15-years-old and older.	8,195
Model D	${\lambda }_y^C\ne {\lambda }_y^Y\ne {\lambda }_y^A$	Age- and time-varying FOI where the FOI across the three age-groups is allowed to freely vary.	6,088

95% exact binomial confidence intervals are shown for the RSV tests.

RSV, respiratory syncytial virus; ILI, influenza-like illness; CI, confidence interval.

DIC, deviance information criterion; FOI, force of infection.
