PEDV outbreak in the US should mean stronger biosecurity guards

摘要

In previous article, I provided a summary of 'issues' around global developments in relation to Porcine Reproductive and Respiratory Syndrome (PRRS), Porcine Epidemic Diarrhea Virus (PEDV) and African Swine Fever (ASF).Since that article, development around PED continues to cause consternation in the United States (US), with producers and regulators at a loss to explain and control the outbreaks.As reported recently, PED is caused by a coronavirus. PED virus (PEDv) is a Transmissible Gastro-Enteritis (TGE) like virus affecting most age groups of pigs in susceptible herds.While the virus does not tend to kill older pigs, mortality among very young pigs infected can vary considerably, with 100% mortalities observed in some herds. When the disease is endemic, then diarrhoea is observed with lower morbidity in predominantlysuckling and recently weaned pigs.
