Figure 4From: Accounting for uncertainty in model-based prevalence estimation: paratuberculosis control in dairy herdsEffect of control on herd level prevalence. The effect of a range of control strategies on the herd level prevalence, 1−p(0) (i.e. the proportion of farms with infected animals) over time. The control strategies are in place throughout the period shown on the x-axis. The strategies shown are: no control (∘), annual ELISA test and cull positive animals (△), infection management by reduction of both calf exposure and infection by clinical animals ( + ), ELISA and infection management together (×) and annual faecal culture test and cull positive animals combined with infection management (◇).Back to article page
