Epidemiologic Aspects of a Foot- and-Mouth Disease Epidemic in Cattle in Ecuador
A case-control study was conducted to identify herd-level risk factors associated with foot-and-mouth disease (FMD) in Ecuador. Case herds were those with presence of cattle with clinical signs of FMD and that tested positive for FMD virus during the epidemic of 2002 (n = 39). Control farms (n = 78) were selected randomly from a list of farms without a history of FMD. All study farms were visited, and managers were interviewed to complete an epidemiologic questionnaire. Feedlot operations, purchase of livestock at markets, and close proximity to markets or slaughter facilities were identified as risk factors for FMD (P ≤ 0.01). In addition to systematic vaccination of the national herd, we recommend allocation of funds for ring-vaccination of cattle herds in close proximity to markets or slaughter facilities, and to enforce movement of vaccinated-cattle only to help control and prevent new epidemics of FMD.
Control of foot and mouth disease: lessons from the experience of the outbreak in Great Britain in 2001.
An epidemic of foot and mouth disease occurred on an unprecedented scale in Great Britain in 2001. This was characterised by widespread dissemination of disease in sheep due to infection being present but unreported for at least three weeks before the first case was identified. As envisaged by the contingency plans, existing procedures dealt rapidly with disease in many parts of the country where outbreaks were reported. Elsewhere, the scale and speed of disease spread was so great that veterinary resources had to be supplemented on the operational front by a large influx of military and administrative support. At the time of writing (June 2002), the United Kingdom Government has already identified a number of key lessons, and will learn further from this experience and from the findings of inquiries, how a future outbreak of this unprecedented nature and extent could be handled. Lessons identified so far relate to the improvement of contingency plans, the wider impact on rural businesses and communities, reassessing the possible use of emergency vaccination, the availability of serological capacity, better animal identification and movement controls, carcass disposal, communications, data handling and management information. The authors present the initial lessons learned and which formed the basis of official submissions to the inquiries. Further lessons will be learned from the findings of those inquiries.
Modelling the potential impact of exotic diseases on regional Australia.
SUMMARY: Recent international initiatives for disease control suggest that, in the future, the consequences for trade of an exotic disease outbreak may not be as severe as estimated in the past. If zoning were to be accepted by Australia's trading partners, then the major effects may be felt at the regional rather than the national level. A study, using an integrated epidemiological/economic model, was undertaken to compare the impacts of 3 important exotic diseases (foot-and-mouth disease, classical swine fever and sheep pox) in 3 different regions of Australia. 
 
 
 
The study demonstrated that there are significant differences between the size and effect of different disease outbreaks. Regional factors influence not only the way that the disease will spread and manifest itself, but also the effects on local communities. Foot-and-mouth disease caused more economic losses than sheep pox or classical swine fever. The major determinant of differences in the effects of the diseases between regions was the nature of the regional economies. The less diversified the economy, the greater the effect of an exotic disease outbreak in relation to the size of that economy.
