Control of the PED virus requires an intelligent biosecurity strategy

摘要

Porcine Epidemic Diarrhoea (PED) is a production disease that only affects pigs; it has no implications for human health. PED started in Europe in the 1970s, then moved throughout Southeast Asia and China. The first US case was reported in Ohio in April 2013, and subsequently it spread to Mexico and Canada.The importance of this disease resides in the worrying economic losses that it can cause to the porcine industry, i.e. the US industry lost more than five million pigs in less than one year.PED is caused by a virus which belongs to the Coronaviridae family, but it is genetically different from transmissible gastroenteritis virus, which is also belonging to Coronaviridae family.
