摘要: Epidemiological modelling is an important approach used by the Veterinary Services of United States Department Agriculture Animal and Plant Health Inspection Service to evaluate potential effectiveness different strategies for handling foot mouth disease (FMD). Identifying spread FMD outbreak, then considering impacts vaccination, in helping inform decision-makers about outcomes vaccination programmes. The objective this study was emergency control a simulated outbreak Minnesota. North American Disease Spread Model (NAADSM, Version 3.2.18) simulate outbreak. Large-scale (1,500 herds per day) reduced size modelled both swine dairy production types, but effect larger when began herd. also overcame limitations caused delays vaccine delivery. Thus, even if did not begin until 21 days into large-scale still duration quantity markedly used, compared with small-scale (50 administration. In addition, number animals vaccinated originating herd substantially lower than beginning cattle.
