Table 5.

Estimated monthly incidence rate per 1000 animals for FMD in SR for each age group.

Age-group (in months)	Prevalence (p)	Average age at (in months)	Proportion of susceptible St = (1-p)	Age related risks* [1-(St/St-1)]	Age-specific monthly incidence rate/1000 animals mt = -ln(1-Rt)/(at – at-1)
6 - <12	0.037	8.86	0.963	0.037	4.2
12 - 24	0.136	19.84	0.864	0.103	9.9
>24	0.213	47.9	0.787	0.089	3.3

^*Age related risks are estimated over different lengths of times within the different age-groups.
