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 shares the 2019-2021 PRRS incidence by state and how it influenced exponentially weighted moving average (EWMA).
- We continue to observe different EWMA patterns across states.
- Iowa, Minnesota and Nebraska are undergoing an epidemic of larger magnitude and duration when compared to the previous year.
- Even though fall and winter continue to be the seasons with overall higher incidence, sporadic cases in warmer months were observed throughout the states.
