1. More data does not automatically make decision-making easier

PRRS management is entering a period of more data and more complex decision-making. Sequencing can reveal relationships among viruses, and surveillance systems can detect new signals, but sequence data alone does not tell a manager when to act. Sample representativeness, testing schedule, pig flow, immune status and clinical presentation all shape interpretation. An effective PRRS control program must connect laboratory results with conditions in the herd.

The 15th Leman China Swine Conference connects these decisions across a three-day PRRS programme. On October 22, 2026, a disease-control forum will examine how sequencing can support PRRSV elimination. On October 23, the PRRS breakout sessions will address maternal immunity and viral evolution, surveillance systems for emerging strains, and the evaluation of interventions. On October 24, sessions will examine biosecurity changes on U.S. farms in response to novel strains, less invasive sample sampling methods for diagnosis, and risk factors for wild-type virus introductions.

2. Turn PRRS test results into action thresholds

The value of face-to-face discussions lies in examining the details that determine whether a PRRS control measure will work: Why was the sample type selected? Is the testing schedule frequent enough to detect change? How do teams distinguish continuing transmission and reintroduction from genetic variation that has limited production significance? When should vaccination, biosecurity or pig flow be adjusted? Experts from the University of Minnesota, Carthage Veterinary Clinic and Swine Vet Center bring research, clinical and production perspectives to these decisions.

International delegates can use the conference to stress-test their own PRRS surveillance systems. Prepare a timeline for one recent event, including clinical signs, production data, sampling locations, laboratory results and actions taken. Compare it with the approaches discussed in the programme. The most useful outcome may not be another test. It may be removing a step that never changes a decision or setting a clearer action threshold for a critical result.

3. Why PRRS control is worth discussing in Zhengzhou

There is no universal PRRS control plan that works in every production system. Production density, pig sources, regional transmission patterns, diagnostic capacity and management execution determine how the same recommendation performs. At the Leman China Swine Conference in Zhengzhou, North American research and clinical experience, Chinese production systems and the wider Asian disease context can be compared within one programme. For anyone designing a regional PRRS strategy or evaluating investment in elimination, this comparison can reduce the risk of adopting a plan that does not fit local conditions.

The 15th Leman China Swine Conference will take place in Zhengzhou, China, from October 22 to 24, 2026. Register to compare PRRS sequencing, surveillance and biosecurity approaches, question implementation details, and strengthen the way PRRS data informs production decisions.
