International trade and travel has literally opened up new vistas for humans, ranging from travel to exotic places to enjoying the products and services of those distant lands. But along with international trade and travel comes the risk of spreading infectious diseases, a growing problem in today's global economy, says an Arizona State University researcher.
"The recent Ebola outbreak made us realize that we are all just a plane ride away from exposure to emerging infectious diseases," says Charles Perrings, an ASU professor of environmental economics. Perrings recently published the paper, "Options for Managing the Infectious Animal and Plant Disease Risks of International Trade," in the early online version of the journal
Food Security.
The paper reported project results to an international conference "Global Plant Health Risks and Consequences: Linking Science, Economics and Policy," hosted by the British Food and Environment Research Agency, and supported by the Organisation for Economic Cooperation and Development's Cooperative Research Programme on Biological Resource Management for Sustainable Agricultural Systems. Perrings is the principle investigator of a project funded by the National Science Foundation-National Institutes of Health-U.S. Department of Agriculture Ecology and Evolution of Infectious Diseases program in collaboration with the UK's Biotechnology and Biological Sciences Research Council.
In the paper, Perrings describes the growth of international trade since the 1950s and the increasingly tight coupling of developed and developing economies. The paper considers how the global community currently deals with trade-related infectious disease risks of animals and plants, and asks how the system could be made more effective.
An example of the impact of an infectious disease came in 2001 in the UK when an outbreak of hoof and mouth disease cost some $10 billion and more than 2 million sheep and cattle had to be destroyed, Perrings said. More recently, African swine fever--a much more serious disease of pigs--has been spread in the Caucasus region through trade in pork, pork product or through waste in trade vehicles.
