Abstract
Safe and effective transportation of livestock during disease outbreaks is crucial for maintaining agricultural productivity and economic stability. This work offers a novel perspective on the transportation of hazardous biological materials within the veterinary field. In response to the complex challenges of managing livestock disease outbreaks, we evaluated different routing measures for safe land transport of diseased animals or infected materials. The potential disease exposure risk to susceptible livestock populations during hypothetical transportation scenarios of infected livestock and specimens was estimated. A GIS-based framework was developed to integrate and manage raster-based Gridded Livestock of the World (GLW) data and vector-based road network data, which was used to implement a time-based risk (TBR) measure to support routing decisions of diseased animals. This approach not only considers time as a traditional routing metric but also incorporates livestock population distribution as a crucial factor in the disease exposure risk assessment. Along with the TBR measure, the shortest, fastest, and least population exposure measures are also evaluated as routing solution benchmarks. Analysis results based on two origin-destination pairs within Oklahoma, USA demonstrate that the TBR measure yields routes with the least impact on animal populations as compared to the shortest, fastest, and least population route, especially over longer distances. Our results underscore the importance of incorporating dynamic exposure risks in routing decisions to effectively minimize potential disease spread to vulnerable populations distributed along the path of transportation. This study also highlights the potential of GIS in enhancing biosecurity and disease control measures by optimizing transportation routes that consider various risk factors.
期刊介绍:
Preventive Veterinary Medicine is one of the leading international resources for scientific reports on animal health programs and preventive veterinary medicine. The journal follows the guidelines for standardizing and strengthening the reporting of biomedical research which are available from the CONSORT, MOOSE, PRISMA, REFLECT, STARD, and STROBE statements. The journal focuses on:
Epidemiology of health events relevant to domestic and wild animals;
Economic impacts of epidemic and endemic animal and zoonotic diseases;
Latest methods and approaches in veterinary epidemiology;
Disease and infection control or eradication measures;
The "One Health" concept and the relationships between veterinary medicine, human health, animal-production systems, and the environment;
Development of new techniques in surveillance systems and diagnosis;
Evaluation and control of diseases in animal populations.
