Table 5 Prevalence of additional classical scrapie (CS) cases by control strategy and country from flocks in which the first scrapie animal had either atypical scrapie (AS) or CS.

From: The prevalence of atypical scrapie in sheep from positive flocks is not higher than in the general sheep population in 11 European countries
