PRRSV – Page 3 – Swine in Minnesota

Updates on monitored PRRSV variants

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.

Porcine Reproductive and Respiratory Syndrome Virus (PRRSV) continues to evolve, posing ongoing challenges for swine health management. This report, brought to you by the MSHMP team, provides an update on several monitored PRRSV variants of interest—1H.18, 1C.2, and 1C.5—along with two recently split variants, 1C.5.32 and 1C.5.36. These updates reflect current detection patterns as of early May 2025, geographic distribution, and clustering activity, helping stakeholders stay informed about trends in variant circulation and transmission dynamics.

How does vehicle Cleaning and Disinfection (C&D) help protect swine 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.

Natalia Martinez, Cesar A. Corzo, Gustavo Machado, Abel B. Ekiri, Inaki Deza-Cruz, and Joaquin M. Prada share a study showing how vehicle cleaning can combat disease spread in this week’s Science Page.

Repeat offenders: PRRSV-2 clinical re-breaks from a whole genome perspective

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.

Today’s Science Page is a breakdown of a recent study done by Julia P. Baker, Albert Rovira, and Kimberly VanderWaal of the University of Minnesota, in which they studied PRRSV-2 re-breaks and how the virus changed over time.
