Emerging PRRS Virus Strains L1C 1-2-4 and Rosalia: Want to Learn More?

Feb 13, 2023

Emerging diseases often come with familiar names coupled with increased risk and need for response. For example, in the U.S., the porcine reproductive and respiratory syndrome virus (PRRSV) L1C variant of RFLP 1-4-4 has been a significant challenge in the Upper Midwest for two years and now PRRSV L1C 1-2-4 has become a concern, the Swine Health Information Center (SHIC) reports. In Spain, a PRRSV strain with increased virulence known as Rosalia has affected production since 2020.

Because of this, SHIC will be hosting a webinar to discuss these emerging PRRSV strains on Tuesday, Feb. 21 at 11 a.m. CT along with the American Association of Swine Veterinarians and Iowa State University’s Swine Medicine Education Center.

Webinar participants include

Dr. Enric Mateu, Autonomous University of Barcelona, Spain
Dr. Daniel Linhares and Dr. Giovani Trevisan, Iowa State University
Dr. Clayton Johnson, Carthage Veterinary Service in Illinois
Dr. Paul Yeske, Swine Vet Center in Minnesota

All have hands-on experience with emerging PRRSV strains and will share their perspectives on clinical presentation, production losses, detection and spread, regional differences, response strategies and what they have found to be successful in control or elimination from herds in the US and potential lessons learned from Spain, SHIC reports.

Video: Secure Pork Supply Plan | Prepare to Protect Your Herd | U.S. Pork Producers

Join Jill Brokaw, a third-generation pig farmer, as she dives into the vital role of the Secure Pork Supply (SPS) Plan in preparing the U.S. pork industry for potential foreign animal disease outbreaks. This video is an essential watch for pork producers who are looking to safeguard their operations against the threats of diseases like foot and mouth disease, classical swine fever, and African swine fever. Why Should Pork Producers Care? An outbreak of foreign animal diseases in the U.S. could lead to severe restrictions and potentially result in industry-wide financial losses estimated between $15 to $100 billion. The SPS Plan is a collective effort to prevent such catastrophic outcomes by enhancing biosecurity, ensuring animal traceability, and promoting effective disease monitoring.
