February Domestic Swine Disease Monitoring Report Now Available

February 6, 2024 — 

The Swine Health Information Center's (SHIC) February Domestic Swine Disease Monitoring Report is available.

This month's Domestic Swine Disease Monitoring Report brings the new chart for weekly monitoring of Influenza A virus PCR detection. The newly implemented monitoring capability provides the industry with information about IAV detection and enables comparison to the historical expected for a specific period. Also, the report brings information about the decreased PRRSV positivity in all age categories, breaking the four consecutive months of increase in the wean-to-market positivity category. However, the average PCR Ct values of the submissions remain low. For the PRRSV ORF 5 sequence, the L1C lineages (L1C.2, L1C.3, L1C.5, L1C-others) remain predominantly detected in the field, and in 2023 accounted for 53% of all wild-type ORF5 sequence detections. For enteric coronaviruses, PEDV positivity had a sharp increase during January in all age categories, raising an alert for the activity of this pathogen. Also, PDCoV had a moderate increase in wean-to-market positivity. Actinobacillus suis entered the top 10 confirmed tissue diagnoses for the first time in the monthly report at ISU-VDL.

In the podcast, the SDRS hosts talk with Dr. Brigitte Mason (Country View Family Farms) about the movement of PRRSV L1C.5 (variant) to the eastern corn belt states and disease management in the winter months.
