Porcine Epidemic Diarrhea Virus (PEDV) is a highly contagious virus that affects pigs, leading to severe diarrhea and dehydration. It primarily impacts young piglets, often resulting in high mortality rates. The virus spreads through contaminated feed, equipment, and the feces of infected animals, making biosecurity measures essential for prevention. First identified in Europe in the 1970s, PEDV has since spread globally, including significant outbreaks in the United States starting in 2013. While there is no specific treatment for PEDV, vaccination and good management practices can help reduce its impact on pig populations and the swine industry.
