The Swine Health Information Center’s (SHIC) July Domestic Swine Disease Monitoring Report is available.
This month’s Domestic Swine Disease Monitoring Report covers the first detection of PRRSV lineage 1C.2 in North Carolina. The PRRSV case positivity in wean-to-finish remains at 40% in June, which is unusually high for the summer. PRRSV case positivity remains above the expected state-specific baselines in Iowa, Minnesota, South Dakota, and Indiana. Although there is decreased PEDV case positivity across all age categories, the percent positive cases from vehicles and truck washes remains high (17%). PDCoV case positivity is above the state-specific baselines in Missouri, Indiana, Ohio, and North Carolina. Mycoplasma hyopneumoniae case positivity increased in wean-to-finish, but most of the positive cases were deep tracheal swabs and lungs collected to prepare homogenate for sow farm exposure. PCV2 and PCV3 case positivity increased moderately with PCV2 being detected predominantly in finishing sites and PCV3 in sow farms.
