Evaluation of the benefit of emergency vaccination in a foot-and-mouth disease free country with low livestock density

摘要: Foot-and-mouth disease (FMD) is highly contagious and one of the most economically devastating diseases cloven-hoofed animals. Scientific-based preparedness about how to best control in a previously FMD-free country therefore essential for veterinary services. The present study used spatial, stochastic epidemic simulation model compare effectiveness emergency vaccination with conventional (non-vaccination) measures Switzerland, low-livestock density country. Model results revealed that radius 3 km or 10 around infected premises (IP) did not significantly reduce either cumulative herd incidence duration if started small situation where number IPs still low. However, has become extensive, both are reduced were implemented IPs. effect different levels strategy was also explored non-vaccination strategy. It found lower compliance level farmers movement restrictions delayed culling increased IP duration. Contingency management should focus mainly on improving strategies, by increasing awareness communication stakeholders teams countries livestock structure similar Switzerland; however, be considered there reasons believe may such as when detection been many discovered at beginning epidemic.
