Porcine Epidemic Diarrhea Virus (PEDV) is a virus of widespread concern, causing diarrhea, vomiting and severe dehydration. The disease has a death rate of 80–100% in infected piglets. PEDV prevention in neonatal pigs is challenging, as the virus is highly infectious and able to survive in the environment, even with strict sanitation practices.
