Science Page: Why are we not making more progress to decrease PRRS incidence?

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 we are sharing a report by Dr. Clayton Johnson from Carthage Veterinary Services on PRRSV incidence and why it has not been decreasing as expected at the past few years.

Key points

  • Enhancing biosecurity increases the chances to prevent PRRS.
  • We have learnt to deal better with the disease and that is reflected by the reduction of the economic impact of PRRS
  • Choose the level of biosecurity that economically better fits to your risk.

In his report, Dr. Johnson identifies 3 main causes that PRRSV incidence is not decreasing.

  1. We can’t Prevent PRRS Infections
  2. PRRS Cost is Decreasing: Tools and Technologies for PRRS Infection Management are Improving
  3. PRRS Prevention Strategies aren’t Cost Effective

To learn more you can read the full report or take a look at Dr. Johnson’s presentation on this very same topic during the 2017 Leman conference:
