Current Status of PED
• PED continues to be a major health challenge for U.S. producers
• Since it was first diagnosed in May of 2013, there have been a total of 2084 cases reported: – CASE reports are different than SITE reports.
– IA = 770; OK = 272; NC = 301; MN = 217; KS = 143
– Data can be found at www.aasv.org

National Pork Board Focus
• Assist in the investigation of source of the virus
• Research on PEDv and impact for US producers
• Development and communication of producer information/resources
• Containment/management strategies
– Work with USDA and develop next steps for emerging disease response
– Other needs?
![Page 5: Dr. Lisa Becton - PEDV: What Can Producers Do To Reduce Their Risk?](https://reader034.vdocuments.mx/reader034/viewer/2022042700/559661f91a28abe7178b4687/html5/thumbnails/5.jpg)
PEDv Research Efforts
• Since June of 2013, the Board has approved $>1 million for use for PEDv since June 2013– Additional $$$ from State Associations
• 2013 research focus:– Study of how PEDv effects pigs
– Development of diagnostic tests for PEDv
– Development of methods to grow the virus (vaccine and test development)
– Survivability in feed, water, manure, slurry, and in trailers
– Methods to kill PEDv/PRRS
![Page 6: Dr. Lisa Becton - PEDV: What Can Producers Do To Reduce Their Risk?](https://reader034.vdocuments.mx/reader034/viewer/2022042700/559661f91a28abe7178b4687/html5/thumbnails/6.jpg)
2013/2014 PEDv research focus
• Fall 2013 – Focus on formation and duration of sow immunity after infection– What level of immunity is needed for full protection?
– How do we measure sow status and response to feedback?
• Spring 2014 – Focus on continued management strategies and surveillance for PEDv– How do we continue to develop/validate diagnostic tests to provide
information on disease status?
– Seed-money for vaccine development
– Evaluate effectiveness of biosecurity interventions

PEDv – what do we know so far?(All research information is posted at www.pork.org/PEDV )
• PEDv spread = fecal/oral
– Transmits through contaminated manure; anything in contact with PEDv + manure can be a potential source of infection
• Rapid spread especially in high density areas!
• Virus survives under different conditions:
– Survive in cold conditions
– Can survive in dry and slurried feed
– Can survive in slurry, feces, water
![Page 8: Dr. Lisa Becton - PEDV: What Can Producers Do To Reduce Their Risk?](https://reader034.vdocuments.mx/reader034/viewer/2022042700/559661f91a28abe7178b4687/html5/thumbnails/8.jpg)
PEDV Research Results
• Fecal shed peaks at 5-6 days post infection and most animals stop shedding virus after 21 days
• Virus is NOT shed in the respiratory tract and not aerosolized…BUT, does it move in the wind on dust particles?
• Virus can be killed at 160°F for 10 minutes OR maintaining them at room temperature (68F) for at least 7 days. (This is without cleaning or disinfection)

Biosecurity Guidelines
• PED is a complex virus to deal with, so create barriers between farm/pigs and potentially contaminated areas
• Line of Separation: is defined as the line between the area that is to be used by the non-farm personnel and the area to be used by farm personnel
– Applies to ANY service (transport; manure haulers etc.)
![Page 10: Dr. Lisa Becton - PEDV: What Can Producers Do To Reduce Their Risk?](https://reader034.vdocuments.mx/reader034/viewer/2022042700/559661f91a28abe7178b4687/html5/thumbnails/10.jpg)

Ongoing Lessons from PEDPreparation for the Next Disease Events
Issues
1. Data confidentiality - Premises ID and permission to use for disease analysis
2. Housing of data, analysis and reporting
3. Cooperation of VDLs when acting as a business center
4. PRV Control Board model for emerging diseases
5. Rapid Response Teams for outbreak investigation
