Values for the duration of the first epizootic, the first epizootic period, and the inter-epizootic interval are shown (see Methods). All values represent the median values (minimum-maximum) for individual counties except where specified differently.
*
The number of counties is less than total due to censoring of data (i.e., not all had defined onset of second epizootic).
