Overall, we found 3.3 outbreaks per 100 ship-weeks, a mean outbreak duration of 4.4 weeks, and a mean cumulative ship population attack rate of 3.6%.

Overall, mean outbreak duration was 4.4 weeks (Poisson Exact 95% C.I.: 2.6, 6.2) and the mean cumulative ship population AR was 3.6% (Poisson Exact 95% C.I.: 3.3, 3.8).

Neither mean incidence (P = 0.29) nor outbreak duration (P = 0.10) explained differences amongst flocks in age-at-onset in ARQ/VRQ animals.

Where significant differences in age at onset for a PrP genotype were identified amongst flocks, Cox proportional hazard models [25] with age-at-onset of clinical signs as the survival measure were used to explore whether mean and peak incidence, outbreak size, outbreak duration and flock type explained these differences.

A number of epidemiological parameters were used to characterise the outbreaks: number of cases; outbreak size (number of cases divided by flock size); mean incidence; peak incidence over a 12 month period; outbreak duration (time between the first and last confirmed cases in the flock); and age-at-onset of cases.

While 39% of outbreaks were of size one, the mean outbreak size was 7.6 individuals and the mean length of an outbreak was 2.8 months.

Outbreak duration was not defined for flocks with singleton cases.
