PRRS prevalence comparison among different MSHMP cohorts

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.

MSHMP Researchers Mariana Kikuti, Xiaomei Yue, Marcello Melini, Emily Geary, and Cesar Corzo break down PRRS prevalence among two cohorts of participating farms in this week’s Science Page.

Can you estimate PRRSV piglet prevalence using family oral fluids? Yes, you can.

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 brings together researchers from three continents! Onyekachukwu Osemeke, Eduardo Costa, Vinicius Weide, Swaminathan Jayaraman, Gustavo Silva, and Daniel Linhares share how to estimate PRRS prevalence at the piglet level in a farrowing room based on the results of family oral fluid testing.

Measures of disease occurrence review

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.

Get re-acquainted with a few of the MSHMP epidemiologic tools! Marcello Melini, Mariana Kikuti, Miranda Medrano, Emily Geary, and Cesar A Corzo of the University of Minnesota review some of the graphic representations used in their weekly reports.

Prevalence comparison among different MSHMP cohorts

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.

University of Minnesota researchers Mariana Kikuti, Miranda Medrano, Marcello Melini, Carles Vilalta, Juan Sanhueza, Emily Geary, Cesar Corzo compare PRRSV disease status between systems that originally shared their sow herd status with MSHMP and those that joined the program later.

Review of MSHMP PRRS Chart 2 ‐ Prevalence.

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.

Key Points: 

  • Chart 2 depicts the prevalence (e.g. the proportion of breeding herd in each of the PRRS status categories over time).
  • Since 2013, the proportion of farms that vaccinate (2vx) and that use field virus (2fvi) has not changed dramatically.
  • The cyclical pattern of farms in status 1 observed early in the program is slowly disappearing after 2019.
