PED – Swine in Minnesota

Active surveillance and impact of an intervention on PEDV occurrence in a large pig production system in the US

Today, we are sharing a recent publication from the MSHMP team led by Dr. Cesar Corzo in collaboration with a US pork producer. The full article is available in open access on the Porcine Health Management journal’s website. The objectives of this study were to actively monitor Porcine Epidemic Diarrhea in pigs during several stages of the finishing phase and to assess the impact of added biosecurity measures.

A Review of MSHMP’s Report PED Chart 3: PED Outbreak History

This is our Friday rubric: every week a new Science Page from the Bob Morrison’s Swine Health Monitoring Project. The previous editions of the science page are available on our website.

This Friday we review MSHMP’s PED Chart 3, which shows the previous PED break history for farms which break with PED during the current year.

Post-epidemic dynamics of PEDV in the United States: Current trends and patterns

This is our Friday rubric: every week a new Science Page from the Bob Morrison’s Swine Health Monitoring Project. The previous editions of the science page are available on our website.

This week, the MSHMP team is sharing what they are observing regarding Porcine Epidemic Diarrhea virus in the US. What are the trends and patterns emerging years after the epidemic?

Main Points

Since July 2014, the number of PEDV yearly outbreaks reduced both numerically and in geographical distribution.
PEDV outbreaks occur seasonally, with most cases being detected during winter.
Spatial-temporal clusters of PEDV outbreaks were detected, most of which occurred prior to 2019.

Porcine epidemic diarrhea (PED) is a swine enteric viral disease first documented in the U.S. swine population in 2013, at which time it sparked a major epidemic. Since then, PEDV has persisted in the U.S. breeding herd with low incidence during the post-epidemic period. Despite continued monitoring and surveillance, there is minimal research and understanding of the endemic phase of PEDV in the country. Our objective was to characterize PEDV in the U.S. breeding herd in the post epidemic period (spatial-temporal distribution of cases and associated factors).

Newly funded: U scientists to enhance forecasting tool for highly contagious porcine disease

Porcine epidemic diarrhea virus (PEDV) is a highly contagious, widespread infectious disease whose transmission routes, due to a dearth of available data, have been largely unpredictable since its emergence in the U.S. in 2013.

A team of University of Minnesota scientists wants to change that. Thanks to recent new funding from the Swine Health Information Center, College of Veterinary Medicine researchers aim to give swine farmers the tools they need to predict the likelihood of an outbreak before it occurs—by using existing and new data to increase the understanding of how the virus spreads through time and space.

ASF and PED alter China swine production: a podcast

Podcasts are a perfect way to get caught up with new swine information! We are presenting you the latest episode from “At The Meeting… Honoring Dr. Bob Morrison” in collaboration with SwineCast.

‘At The Meeting’ Honoring Dr. Bob Morrison focuses on how African Swine Fever (ASF) and Porcine Epidemic Diarrhea virus (PEDv) have driven changes in farm design and biosecurity in China, allowing China’s swine industry to regain an estimated 80 percent of its swine herd.
