The Swine Health Information Center has introduced a tool that provides insight into the evolution and distribution of specific strains of Porcine eproductive and Respiratory Syndrome over time, space and age groups.The Swine Health Information Center's May domestic swine disease monitoring report, released as part of its monthly eNewsletter, highlights a spike in PRRS virus case positivity in April in wean-to-finish sites and notes, compared to previous years, it was the highest April case positivity since 2018.
SHIC Associate Director Dr. Lisa Becton says the report includes a bonus page which explains the new PRRS virus nomenclature and its implementation in the swine disease reporting system dashboards and BLAST tool.
Quote-Dr. Lisa Becton-Swine Health Information Center:
The bonus page provides highlights and insight into PRRS evolution and distribution of specific strains over time, space and age groups.What this does is it enhances the ability for epidemiologic tracking of outbreaks, it can identify emerging variants and provides insights into genetic relationships between the different sequences that are identified over time.
