Tank level descriptions of epidemics.

Percentage of replicates in which transmission occurred from the primary infected to exposed fish, time for all hosts in a replicate to become infected (and range), average time to peak (suprapopulation) parasite load, mean maximum parasite burden per tank and extinction day (and range) across different tanks (n) per treatment. + indicates the two longest running replicates; frequent screening ceased on day 74 or 77, thereafter screened every 2 weeks, but both of these tanks went extinct by day 98.
