Can we effectively eliminate influenza from farms?

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.

In this new episode, multiple strategies to eliminate swine influenza from farms are discussed.

PRRS incidence in status 4 sow farms

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 updates a valuable statistical parameter: the PRRS incidence in status 4 status 4 sow farms. As a reminder, status 4 farms are defined as negative for PRRS in both exposure and shedding status.

Key Points

  • In the last 13 years, on average 9.3% (Range 3.2% – 20.3%) of status 4 farms have had a PRRS outbreak, with an apparent cyclical peak at around 10% every 2-3 years.
  • The cumulative incidence of the current MSHMP year (July 2020 to May 2021) for status 4 farms is 9.9%.
  • PRRS incidence in status 4 farms during the current MSHMP season is not higher than the ones observed in the previous MSHMP seasons.

Temporal stability of swine movement networks in the U.S.

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, Dr. Dennis Makau from the VanderWaal lab is sharing a project on the importance of swine movement to identify farms with a high risk of disease outbreak.

Key Points

  • Animal movement is a key factor in the U.S. swine industry and is an important risk factor for disease transmission
  • Animal movement data combined with social network analysis can inform risk-based surveillance and control
  • Using production system movement data, it was possible to identify the time window of data needed to gauge connectivity and identify high-risk and high-spread farms
  • Using previous data up to two years old is still better than choosing randomly implemented interventions to manage disease spread, especially in cases of outbreaks transmitted via animal movements

Assessing Senecavirus A shedding and transmission in growing pig populations

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, Drs. Preis and Corzo are inviting you to participate in an AASV-funded project regarding the epidemiology of Senecavirus A in growing pigs.
