Surveillance of Classical Swine Fever (CSF) should not only focus on livestock, but must also include wild boar. To prevent disease transmission into commercial pig herds, it is therefore vital to have knowledge about the disease status in wild boar. In the present study, we performed a comprehensive evaluation of alternative surveillance strategies for Classical Swine Fever (CSF) in wild boar and compared them with the currently implemented conventional approach. The evaluation protocol was designed using the EVA tool, a decision support tool to help in the development of an economic and epidemiological evaluation protocol for surveillance. To evaluate the effectiveness of the surveillance strategies, we investigated their sensitivity and timeliness. Acceptability was analysed and finally, the cost-effectiveness of the surveillance strategies was determined. We developed 69 surveillance strategies for comparative evaluation between the existing approach and the novel proposed strategies. Sampling only within sub-adults resulted in a better acceptability and timeliness than the currently implemented strategy. Strategies that were completely based on passive surveillance performance did not achieve the desired detection probability of 95%. In conclusion, the results of the study suggest that risk-based approaches can be an option to design more effective CSF surveillance strategies in wild boar.
猪瘟（CSF）监测不仅应集中于家畜，还必须包括野猪。为了防止疾病传入商业猪群，了解野猪的疾病状况至关重要。在本研究中，我们对野猪中猪瘟（CSF）的替代监测策略进行了全面评估，并将其与当前实施的常规方法进行了比较。评估方案是使用 EVA 工具设计的，这是一种决策支持工具，可帮助制定用于监测的经济和流行病学评估方案。为了评估监测策略的有效性，我们研究了它们的敏感性和及时性。分析了可接受性，最后确定了监测策略的成本效益。我们为现有方法和新提出的方法之间的比较评估制定了 69 种监测策略。仅在亚成体中采样比目前实施的策略具有更好的可接受性和及时性。完全基于被动监测性能的策略无法达到 95%的期望检测概率。总之，研究结果表明，基于风险的方法可以作为设计更有效的野猪 CSF 监测策略的选择。
