“…1a). Such physical borders with no fences in between were previously shown within the same area to temporarily slow the speed of CSFV spread, but not to prevent virus invasion, possibly due to the continuity of forested areas facilitating the crossing of terrestrial wildlife (Rossi et al, 2010). Therefore, we assume that few infected wild boar crossed this imperfect barrier, generating a particular strain selection that was based on the limitation of the host's movements rather than on selection pressure on the virus itself.…”

“…In detail, oral emergency vaccination was implemented in the first infected area starting in August 2004 (Fig. 1a), and the area was enlarged in January 2005 to cover all forested areas at risk (Pol et al, 2008;Rossi et al, 2010). From 2005 to 2010, three vaccination campaigns were applied per year and the last positivevirus isolation case was recorded in May 2007 (La Petite Pierre municipality).…”

Classical swine fever is a viral disease of pigs that carries tremendous socio-economic impact. In outbreak situations, genetic typing is carried out for the purpose of molecular epidemiology in both domestic pigs and wild boar. These analyses are usually based on harmonized partial sequences. However, for high-resolution analyses towards the understanding of genetic variability and virus evolution, full-genome sequences are more appropriate. In this study, a unique set of representative virus strains was investigated that was collected during an outbreak in French free-ranging wild boar in the Vosges-du-Nord mountains between 2003 and 2007. Comparative sequence and evolutionary analyses of the nearly full-length sequences showed only slow evolution of classical swine fever virus strains over the years and no impact of vaccination on mutation rates. However, substitution rates varied amongst protein genes; furthermore, a spatial and temporal pattern could be observed whereby two separate clusters were formed that coincided with physical barriers.

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.

“…Successful examples are the oral rabies vaccine (which has largely eradicated enzootic rabies among mesocarnivores in several Western European countries, and halted its westward expansion in the eastern United States [15]) and the classical swine fever oral vaccine (which has eradicated that disease among most free-ranging wild boar [Sus scofa] populations in Germany and France [16]). Both these vaccines provide effective protective immunity after a single dose and the immunity established is sufficiently long-lasting that regular vaccine boosting is unnecessary.…”
