The Swine Health Information Center’s (SHIC) March Domestic Swine Disease Monitoring Report is available.
This month’s Domestic Swine Disease Monitoring Report incorporates a new category for PEDV and PDCoV PCR detection: facilities. This new category includes PCR tests from truck washes, vehicles, and packing plants. With this new facility category, SDRS can monitor enteric coronavirus activity from outside the farms. The report includes a bonus page explaining the latest charts for the facility category. PEDV and PDCoV case positivity increased in the new facility category. Also, PEDV and PDCoV overall positivity was above expected in Indiana. The report brings information about the decreased case positivity of PRRSV in wean-to-finish sites. However, PRRSV lineage 1C.5 is spreading rapidly in 2025, exhibiting a historical record compared with the beginning of previous years. Influenza A case positivity increased in all age categories, with the highest positivity coming from wean-to-finish sites (33%).
In the podcast, Dr. Tyler Bauman, herd veterinarian with The Maschhoffs, discussed health management strategies in finishing sites for control and elimination of Mycoplasma hyopneumoniae, IAV, PEDV, and PRRSV, including the different clinical implications of PRRSV L1C.2 and L1C.5.
